Seasonal fatty acid profiles of Penaeus semisulcatus and Metapenaeus monoceros were investigated. Palmitic (16:0), stearic acid (18:0), oleic (18:1), palmitooleic acid (16:1), arachidonic acid (20:4), eicosapentaenoic (EPA, 20:5 n-3) and docosahexaenoic acid (DHA, 22:6 n-3) were found to be the most abundant fatty acids in both shrimp species. Fatty acid profile showed seasonal changes. The highest EPA DHA contents were recorded during winter (January) in both species.

Growing up in a farm environment is protective against allergy development. Various explanations have been put forward to explain this association. Fatty acids are regulators of immune function and the composition of fatty acids in the circulation system may affect immune development. Here, we investigate whether the fatty acid composition of cord serum differs for infants born to Farm (n = 26) or non-Farm mothers (n =29) in the FARMFLORA birth-cohort. For comparison, the levels of fatty acids in the maternal diet, serum and breast milk around 1 month post-partum were recorded. The fatty acids in the cord sera from infants born to Farm mothers had higher proportions of arachidonic acid (20:4 n-6) and adrenic acid (22:4 n-6) than those from infants born to non-Farm mothers. No differences were found for either arachidonic acid or adrenic acid in the diet, samples of the serum, or breast milk from Farm and non-Farm mothers obtained around 1 month post-partum. The arachidonic and adrenic acid levels in the cord blood were unrelated to allergy outcome for the infants. The results suggest that a farm environment may be associated with the fatty acid composition to which the fetus is exposed during pregnancy.

Three species of red marine macro algae (Rhodophyta) from the Indian Ocean were analysed for the occurrence of conjugated polyenes. The composition of different lipid classes in these seaweeds along with their fatty acid composition has also been reported. Analysis of lipid classes of these seaweeds revealed that both Acanthophora spicifera (Ceramiales, Rhodophyta) and two species of Gracilaria, viz. G. edulis and G. folifera (Gracilariales, Rhodophyta) were rich in glycolipids followed by neutral- and phospholipids. The fatty acid composition of these seaweeds revealed C16:0 as the predominant fatty acid in all three species. However, A. spicifera had significantly higher amounts of eicosapentaenoic acid (EPA) and arachidonic acid (AA) as compared to negligible amount of these fatty acids in both species of Gracilaria. The red seaweed Acanthophora spicifera contained conjugated eicosapentaenoic acid (CEPA) and conjugated arachidonic acid (CAA) in all lipid classes except glycolipids.

The fatty acid compositions of the total, neutral, and polar lipids of Blastocladiella emersonii have been determined. Major fatty acids were palmitic, oleic, linoleic, γ-linolenic, and arachidonic acid. Polar lipid contained a higher proportion of linoleic, γ-linolenic, and arachidonic acid than did neutral or total lipids, whilst neutral lipid had a high proportion of palmitic and oleic acid. In addition to γ-linolenic acid, α-linolenic acid was also present; this is the first occasion that both isomers have been demonstrated in the same fungus, and the phylogenetic possibilities of this finding are discussed.

Fatty Acid Compositions

The fatty acid compositions of lipids from an isolated population of inshore cod (Gadus morhua L.) caught near Terence Bay, Nova Scotia, were determined each month on pooled samples of representative fish. Cod liver oil was studied over a period of 17 months, cod flesh for 12 months with the fatty acid compositions of milt, roe, flesh, and liver lipids being determined from some large, individual fish.The fatty acids of flesh lipids were independent of sex and showed very little, if any, seasonal changes except a slight variation in the long-chain monounsaturated acid 20:1 (max 2.8% vs. avg 1.6% and 1.1%). This was especially evident in large fish where the maximum (3.7%) coincided with the period of best "condition," August to November. There was also a significant difference between large and medium size fish in that in very large fish the content of 22:6 was much lower (26% vs. 33%). Liver oils in female fish contained increasing amounts of 20:1 (4.5 to 14.9%) and 22:1 (1.8 to 12.3%) fatty acids with increased fat content of the liver, maxima occurring in late summer and fall. In the male fish this seasonal trend was not as obvious. No other acids showed any definite seasonal variation. In the fatty acids of roe and milt lipid no definite relationship could be established between ripening and fatty acid composition. The fatty acids of the milt were similar to the roe except for a higher percentage of 18:1 and lower percentage of 16:1. The unsaponifiable matter was higher in milt than in roe lipids.These results indicate that due to the large variations that can occur in the fatty acid content of lipids from individual fish, a single analysis could give a fatty acid composition quite different from the average of a large number of determinations.

A neuronal nuclear fraction (N1) and a glial nuclear fraction (N2) have been isolated from 15-day-old rabbit cerebral cortex using the Thompson procedure. More than 56% of the homogenate DNA was recovered in the two nuclear fractions, with N1 being the larger by about eightfold. Fractions N1 and N2 had very similar phospholipid distributions, with phosphatidyl-inositol being a larger component than phosphatidylserine. Fatty acid analyses demonstrated that phosphatidylethanolamine and phosphatidylinositol, individually, had similar fatty acid profiles in fractions N1 and N2, and also in nuclear and microsomal fractions derived from homogenates of nerve cell bodies isolated from cerebral cortex of 15-day-old rabbits. In contrast, the nuclear phosphatidylcholines had lower levels of palmitate and higher levels of arachidonate than did microsomal phosphatidylcholines. Molecular species analyses indicated that monoenes (41 mol%), tetraenes (20 mol%), and saturates (13 mol%, composed chiefly of palmitate) were the principal classes of N1 phosphatidylcholines, while the diacyl species of phosphatidylethanolamine of this fraction were characterized by high levels of tetraenes (44 mol%), pentaenes (17 mol%), and hexaenes + polyenes (24 mol%). The neutral glycerides of fraction N1 occurred collectively at a level of 0.05 mol/mol phospholipid. Prominent fatty acids of diacylglycerols included palmitate (31%), oleate (20%), arachidonate (14%), and stéarate (13%). Triacylglycerols showed a similar pattern but with relatively high levels of linoleate (11%), while monoacylglycerols consisted almost entirely of palmitate (33%), stearate (35%), and oleate (24%).

This study has investigated the influence of dietary fatty acid composition on mammary tumour incidence in N-ethyl-N-nitrosourea (ENU)-treated rats and has compared the susceptibility to dietary fatty acid modification of the membrane phospholipids phosphatidylinositol (PI) and phosphatidylethanolamine (PE) from normal and tumour tissue of rat mammary gland. The incidence of mammary tumours was significantly lower in fish oil- (29%), compared with olive oil- (75%; P < 0.04) but not maize oil-(63%; P < 0.1) fed animals. No differences in PI fatty acid composition were found in normal or tumour tissue between rats fed on maize oil, olive oil or fish oil in diets from weaning. When normal and tumour tissue PI fatty acids were compared, significantly higher amounts of stearic acid (18:0) were found in tumour than normal tissue in rats given olive oil (P < 0.05). A similar trend was found in animals fed on maize oil, although differences between normal and tumour tissue did not reach a level of statistical significance (P < 0.1). In mammary PE, maize oil-fed control animals had significantly higher levels of linoleic acid (18:2n−6) than either olive oil- or fish oil-fed animals (P < 0.05, both cases) and levels of arachidonic acid were also higher in maize oil- compared with fish oil-fed animals (P < 0.05). In tumour-bearing animals no differences in PE fatty acid composition were found between the three dietary groups. When normal and tumour tissue PE fatty acids were compared, significantly lower amounts of linoleic acid (18:2n-6; P < 0.01) and significantly greater amounts of arachidonic acid (20:4n−6; P < 0.05) were found in tumour than normal tissue of rats fed on maize oil. The present study shows that the fatty acid composition of PI from both normal and tumour tissue of the mammary gland is resistant to dietary fatty acid modification. The PE fraction is more susceptible to dietary modification and in this fraction there is evidence of increased conversion of linoleic acid to arachidonic acid in tumour compared with normal tissue. Lower tumour incidence rates in rats given fish oils may in part be due to alteration in prostanoid metabolism secondary to displacement of arachidonic acid by eicosapentaenoic acid, but PE rather than PI would appear to be the most likely locus for diet-induced alteration in prostanoid synthesis in this tissue. Effects of dietary fatty acids other than on the balance of n−6 and n−3 fatty acids, and on prostanoid metabolism, should also be considered. The significance of increased stearic acid content of PI in tumours of olive oil-fed animals and the possible influence of dietary fatty acids on the capacity for stearic acid accumulation requires further study.

Seasonal changes of the lipid and fatty acid composition of Pleurobrachia pileus investigated monthly from March 2012 to February 2013. Average total lipid content was determined as percentage (%) and per individual (mg ind-1). It was highest in February (1.48 %; 3.55 mg ind-1). However, it was proportionally the lowest in April (0.40 %), and per individual in August (0.33 mg ind-1). Major fatty acids of P. pileus were identified as 16:0, 14:0, 11:1 n-9c, 20:5 n-3, and 22:6 n-3. P. pileus had on average 27.27 % ∑SFA, 25.04 % ∑MUFA and 47.63 % ∑PUFA content. EPA and DHA were the major fatty acids from PUFA. Seasonal changes of DHA were more obvious than EPA (p<0.05). Herbivore calanoid zooplankton trophic markers; 20:1 n-9 and DHA/EPA and herbivory trophic markers; EPA and DHA content were high in P. pileus fatty acids. It showed that herbivory fatty acids were taken by feeding from herbivory zooplankton and phytoplankton. Diet was an important factor in seasonal fatty acid changes of P. pileus. In addition, we revealed that P. pileus has a rich lipid content and fatty acid composition and plays an important role in the Southeastern Black Sea ecosystem functionalities between herbivory and carnivory species.

Abstract. Nowadays, meat and meat products from indigenous pig breeds are desired by consumers for their high sensory quality. For that reason, the trend to use indigenous pig breeds for production of these products has widened. The aim of this study was to compare physical and chemical parameters of Musculus longissimus dorsi (MLD) as well as content of cholesterol and fatty acid profiles among Mangalitsa, the crossbreed Mangalitsa × Duroc, and pig meat breed Slovak Large White with Polish indigenous breeds Pulawska and Zlotnicka spotted. In the study, 48 pigs were used. The pigs were divided into 5 groups of different genotypes: Mangalitsa breed (n = 9), the crossbreed Mangalitsa × Duroc (n = 9), Slovak Large White – SLW (n = 10), Zlotnicka spotted (n = 10) and Pulawska (n = 10). The pigs were reared under intensive conditions, and they were fed by an ad libitum system with complete feed mixtures. The fattening period lasted from 30 to 100 kg of live weight. The SLW had the highest average daily gain with the lowest feed intake compared to Mangalitsa, the crossbreed Ma × Du and Polish indigenous breeds (P < 0.001). SLW had the highest meat content in the carcass while Mangalitsa had the lowest (P < 0.001). Mangalitsa and their crossbreed Ma × Du had the highest fat content in the carcass, but the SLW and Polish indigenous pig breeds had the lowest fat content in the carcass (P < 0.001). As regards the physical properties of MLD, the Polish indigenous pig breeds achieved the highest values of pH45 min post mortem, the lowest drip loss values, the lowest colour values of CIE L* and the highest values of CIE b* compared to other genotypes in the experiment (P < 0.001). However the meat of crossbreed Ma × Du had pale, soft and exudative (PSE)-like conditions due to the low pH45 min post mortem, the high values of drip loss and CIE L*. The crossbreed Ma × Du and Polish indigenous pig breeds had the highest content of intramuscular fat in MLD compared to Mangalitsa and SLW (P < 0.001). The cholesterol content in MLD was the highest in Polish pig breeds and the lowest in SLW (P < 0.001). Regarding the fatty acid content in the meat, intramuscular fat (IMF) from Zlotnicka spotted was significantly the most polyunsaturated with the highest percentages of C18:2n-6, C20:5n-3 and C22:6n-3, and it had the lowest percentages of monounsaturated fatty acids (MUFAs) as well as contents of C18:1cis-9 and C18:1trans-11 compared to other genotypes (P < 0.001). IMF from Slovak Large White was the most saturated and monounsaturated with the highest content of C18:1cis-9, and it has the lowest percentages of polyunsaturated fatty acids (PUFAs) in IMF compared to genotypes in the study (P < 0.001). From the results, it follows that the Polish indigenous pig breeds are more suitable for the breeding and production of special meat products due to acceptable fattening and carcass parameters as well as the meat quality. As regards fatty acid composition of meat, the direct influence between fatty acid composition in diet and in Musculus longissimus dorsi was not determined. However, the genotypes have a significant impact on fatty acid profiles in MLD.

ABSTRACT Background The health benefits of substituting dietary polyunsaturated fatty acids (PUFAs) for saturated fatty acids are well known. However, limited information exists on how the response to dietary intake of linoleic acid (LA; 18:2n–6) is modified by polymorphisms in the fatty acid desaturase (FADS) gene cluster. Objectives The aim of the current study was to test the hypothesis that the FADS1 rs174550 genotype modifies the effect of dietary LA intake on the fatty acid composition of plasma lipids, fasting glucose, and high-sensitivity C-reactive protein (hsCRP). Methods Associations were investigated between genotype, plasma PUFAs, fasting glucose, and hsCRP concentrations in the cross-sectional, population-based Metabolic Syndrome in Men cohort (n = 1337). In addition, 62 healthy men from the cohort who were homozygotes for the TT or CC genotype of the FADS1 rs174550 were recruited to a 4-wk intervention (FADSDIET) with an LA-enriched diet. The fatty acid composition of plasma PUFAs and concentrations of plasma fasting glucose, serum hsCRP, and plasma lipid mediators (eicosanoids and related analogs) were measured at the beginning and end of the 4-wk intervention period. Results In the FADSDIET trial, the plasma LA proportion increased in both genotype groups in response to an LA-enriched diet. Responses in concentrations of serum hsCRP and plasma fasting glucose and the proportion of arachidonic acid (20:4n–6) in plasma phospholipids and cholesteryl esters differed between genotype groups (interaction of diet × genotype, P < 0.05). In TT homozygous subjects, plasma eicosanoid concentrations correlated with the arachidonic acid proportion in plasma and with hsCRP (r = 0.4–0.7, P < 0.05), whereas in the CC genotype there were no correlations. Conclusions Our findings show that the FADS1 genotype modifies metabolic responses to dietary LA. The emerging concept that personalized dietary counseling should be modified by the FADS1 genotype needs to be tested in larger randomized trials. The study was registered at clinicaltrials.gov as NCT02543216.
