The total lipid content of the dry weight of whole cysts and 2nd-stage juveniles (J2) of Globodera rostochiensis was 17·1% in dry cysts, 20·9% in cysts soaked in distilled water (DW), 20·3% in cysts that had been in potato root diffusate (PRD) for 7 days, 7·3% in cysts that had been in PRD for 28 days and 29·2% for hatched J2. The fatty acid composition of the total lipid did not differ between dry cysts, cysts in DW and cysts in PRD for 7 days. However, major differences in the fatty acid composition of all lipid classes were found between rehydrated cysts in PRD and freshly hatched J2. After hatching, the degree of saturation and the percentage of monounsaturated fatty acids decreased and the percentage of polyunsaturated fatty acids increased considerably, especially in the free fatty acid fraction, where C20[ratio ]1 showed an 8-fold decrease and C20[ratio ]4 a 33-fold increase. There was a difference in the fatty acid composition of cysts in PRD for 7 days and cysts in PRD for 28 days (after most of the J2 had hatched); with increased time in PRD the percentage of polyunsaturated fatty acids increased and the percentage of monounsaturated fatty acids decreased in all lipid classes. Differences in the fatty acid profiles between cysts in PRD for 28 days and hatched J2 were found mainly in the free fatty acid and the non-acidic phospholipid fractions. The free fatty acid fraction of the cysts was dominated by monounsaturated fatty acids (52%), whereas the same fraction of hatched J2 contained large amounts of polyunsaturated fatty acids (60%). These polyunsaturated fatty acids, especially C20[ratio ]4, might play an important part in nematode–plant interactions during infection.

Age Related

Age-related alterations of fatty acid composition in liver and brain of AKR mice was investigated. The effect of savory essential oil (Satureja hortensis L.), added with drinking water on fatty acid composition in these organs and the processes of lipid peroxidation in erythrocytes were estimated. It was found that during aging the percentage of saturated fatty acids and polyunsaturated fatty acids decreased while monounsaturated fatty acids increased. The development of leukemia was accompanied by the increase of saturated and polyunsaturated fatty acids percentage and a decrease of monounsaturated fatty acids amount. In the liver aging caused the increase in the percentage of saturated fatty acids, the decrease of monounsaturated fatty acids, while the amount of polyunsaturated fatty acids was not changed. Leukemia (after 8 month) was accompanied by the increase of percentage of monounsaturated fatty acids and the decrease in the amount of oleinic and docosohexaenic acids. The intake of savory essential oil was accompanied by intensification of polyunsaturated fatty acids synthesis in mice liver and reduction of lipid peroxidation products content.

Status of Mytilus galloprovincialis populations in the natural habitat is known to directly depend on development of Black Sea mussel at all its stages, including initial stages of larval ontogenesis, which are very sensitive to environmental pollution. Organic pollutants adversely affect mussel larvae by inhibiting their growth and development. Patterns of mussel reproduction are well studied, which makes it possible to obtain larvae from artificially fertilized eggs of this mollusc species in controlled laboratory conditions. In this work, the fatty acid composition of M. galloprovincialis larvae at the trochophore stage on the 3rd day in the control experiment and under artificial contamination with polychlorinated biphenyls (PCBs) in different concentrations is studied for the first time. The fatty acid composition of total lipids in the biomass of larvae obtained on the 3rd day of the experiment was studied by means of gas chromatography – mass spectrometry. Totally, 14 fatty acids were identified in the samples; 59 % of them were saturated fatty acids, 24 % were monounsaturated fatty acids, and 17 % were polyunsaturated fatty acids. Statistical analysis was performed using Statistical Toolbox of MATLAB software (version 8.2). The totals of monounsaturated and polyunsaturated fatty acids significantly differed in lipids of M. galloprovincialis trochophores in the experiment with different PCB concentrations. The totals of saturated fatty acids did not significantly differ. The major saturated fatty acids in all mussel trochophores studied were palmitic (C16:0) and stearic (C18:0) acids. Their concentration did not significantly change under the exposure to PCBs. The main monounsaturated fatty acids were oleic (C18:1ω9), palmitoleic (C16:1ω7), and vaccenic (C18:1ω7) acids. The fraction of monounsaturated fatty acids was twice as low when exposed to the PCB concentrations 0.1 and 1.0 μg·L−1. However, when the PCB concentration was 10 μg·L−1, the total of these acids did not differ from the control. Among polyunsaturated fatty acids having biological essentiality, it was possible to identify arachidonic (C20:4ω6), eicosapentaenoic (C20:5ω3), and docosahexaenoic (C22:6ω3) acids. The total fraction of omega-3 and omega-6 acids in mussel larvae in the control did not exceed 12.8 %. With an increase of the PCB concentration in the growth medium 0.1 to 1.0 μg·L−1, the fraction of polyunsaturated fatty acids increased 2.5-fold. At the PCB concentration 10 μg·L−1 and in the sample with pure acetone added, the total fraction of polyunsaturated fatty acids was comparable with that in the control. The results of the study indicate that fatty acid response is the highest when the medium is exposed to the PCB concentrations ranging 0.1 to 1.0 μg·L−1. At the PCB concentrations equal to 10 μg·L−1 or higher, biochemical processes in larvae seem to slow down. The results of this study will contribute to a better understanding of biochemical rearrangements that allow molluscs at larval developmental stages to adapt to environmental pollution with organic xenobiotics.

Abstract. This study investigated the effects of breed on the fatty acid compositions of the Longissimus thoracis et lumborum (LTL) of gilts and barrows. Although only one muscle was analyzed, the results gave a good indication of the effect that breed and sex may have on the fatty acid compositions of the meat. Breed exhibited a significant effect on the fatty acid composition of pigs, whereas the effects of sex were found to be minor. Higher contents of intramuscular fat (IMF), C16 : 1, C18 : 1 and monounsaturated fatty acids (MUFAs); darker color of meat; and lower cholesterol content, drip loss, C18 : 0, C18 : 2, polyunsaturated fatty acids (PUFAs), n-6 and n-6 : n-3 ratios were found in the LTL muscle of Pulawska pigs compared with Polish Landrace pigs. Meat of Pulawska pigs is especially suitable for the production of good-quality, cured and smoked loin for longer storage. Fat content was higher in barrows than in gilts, and as a consequence the IMF from barrows had higher saturated fatty acid proportions and hypercholesterolemic acids (OFAs) as well as lower C18 : 1 than that from gilts.

The study was carried out to compare the fatty acid composition of the breast meat in two lines of slow growing chickens - La Belle (LB) and Bresse (BB), reared conventionally or having access to pasture. The differences in the lipid profile due to the lines and rearing strategies were assessed through two-way ANOVA. Both factors influenced the lipid composition in the breast meat, however the effect of pasture was more pronounced. It was associated with lower contents of C14:0, C16:0 and C16:1Δ7 (P<0.001), C18:1 (P<0.05), total saturated (SFA) and monounsaturated fatty acids (MUFA) (P<0.01), and significant increase (P<0.001) of the long chain polyunsaturated fatty acids (PUFA). These changes in the lipid profile of the breast meat in the chickens reared outdoors led to considerably lower atherogenic and thrombogenic indices, reduced n-6/n-3 ratio (P<0.001), as well as higher P/S and h/H values (P<0.001). Differences in the fatty acid composition of the breast meat were also due to the line of the birds, showing advantage of the LB over BB chickens. The former had lower contents of saturated (P<0.001) but higher long chain polyunsaturated fatty acids (P<0.05) which determined better nutritional indices of the breast meat in the LB line.

The fatty acid composition of newly emerged Ips paraconfusus Lanier shows no sexual dimorphism and is approximately as follows: C14:0, 0.5%; C16:0, 23.0%; C16:1, 6%; C18:0, 3%; C18:1, 55%; C18:2, 9%; C18:3, 2%. Both sexes, but particularly the female, use up fatty acids, particularly the monounsaturated acids, during reproduction. Isotope from 1-14C-acetate injected into newly emerged females appeared in all saturated and monounsaturated fatty acids within 30 min. There was evidence of de novo synthesis of C14:0 and C16:0, chain elongation of C16:0 to C18:0, and desaturation of C16:0 and C18:0 to yield C16:1 and C18:1 respectively.

Selection For

Genetic parameters were estimated for fatty acid composition of subcutaneous beef fat of 1573 animals which were the progeny of 157 sires across seven breeds grown out on pasture and then finished on either grain or grass in northern New South Wales or in central Queensland. There was genetic variation in individual fatty acids with estimates of heritability for the proportions of C14 : 0, C14 : 1c9, C16 : 0, C16 : 1c9, C18 : 0 and C18 : 1c9 fatty acids in subcutaneous beef fat of the order of 0.4 or above. Also substantial correlations between some fatty acids were observed. Genetic correlations between fatty acids and fat depth at the P8 site suggested that much of the genetic variation in fatty acid composition was related to changes in fatness. Selection for decreased fatness resulted in decreased proportions of C18 : 1c9 with concomitant increases in C18 : 0, C14 : 0 and C16 : 0. This suggested that selection for decreased fatness at a given weight will result in a decrease in the proportions of monounsaturated fatty acids in the subcutaneous fat in the carcass with a corresponding increase in the proportions of saturated fatty acids.

The aim of this study was to provide information on the fatty acid profile of different adipose depots - subcutaneous (upper and inner backfat layers) and intramuscular (m. Longissimus dorsi) in East Balkan pigs. The animals were reared in free-range conditions and slaughtered at an average live weight of 107?1.65kg. The results of the study showed that the various adipose tissues in pigs have different lipid metabolism and hence differ in their fatty acid composition. Intramuscular fat had significantly higher content of the saturated C16:0 and C18:0 (P<0.001), as well as the C16:1 (P<0.001) than the subcutaneous fat. In regards to the content of the polyunsaturated fatty acids, the latter displayed considerably higher content of both C18:2 and C18:3 (P<0.001) in comparison to the intramuscular fat in m. Longissimus dorsi. The differences between the subcutaneous and intramuscular adipose tissue in the individual fatty acids determined the similar trend of change in the total content of saturated and polyunsaturated fatty acids. Significant differences between the backfat layers were detected for C16:1, C18:0 and C18:3 (P<0.001). Stearic acid (C18:0) displayed higher content of the inner, while both C16:1 and C18:3 had higher proportion in the outer backfat layer in the East Balkan pigs. Except for C20:2, the long chain polyunsaturated n-6 and n-3 fatty acids had significantly higher proportions in the intramuscular fat, however no differences were determined between the two backfat layers.

Abstract Introduction. With due consideration of the properties of fatty acids, as well as their importance for normal life activity and human development, research into the fatty acid composition of poorly studied plants and the search for new domestic plant sources of polyunsaturated fatty acids is a mainstream trend in modern pharmacy. Aim. Aim of research – determination of fatty acid qualitative composition and content in threshed grass, stalks, roots and seeds of Night-scented stock ‘Queen of Night’ and ‘Evening Scent’ cultivars as grown in Ukraine. Methods. Gas chromatography. Results. Both cultivars of Night-scented stock taken for analysis had similar fatty acid composition – 5 saturated, 5 (4 for seeds) monounsaturated and 2 polyunsaturated fatty acids, Quantitatively, in all tested parts of the herb polyunsaturated and monounsaturated fatty acid dominated, making in total 88.92% and 88.62% in the seeds of Queen of Night and Evening Scent cultivars, respectively, and averaging 65% in other parts of the tested cultivars. Linolenic and linoleic acids prevailed among the polyunsaturated fatty acids, whereas oleic acid prevailed among the monounsaturated. Conclusion. Night-scented stock can be utilized as a source of polyunsaturated fatty acids for the development of drugs and for standardization of tested raw materials.

Abstract In this report, we have compared the fatty acid composition of the endemic Lake Baikal amphipods Ommatogammarus albinus (Dybowsky, 1874) and Parapallasea lagowskii (Dybowsky, 1874). Specimens were sampled using the deep-water manned submersible “Mir” at the oil-methane seeps of Cape Gorevoy Utes and at a hydrothermal vent in Frolikha Bay. High levels of monounsaturated fatty acids and relatively low levels of saturated and polyunsaturated fatty acids were detected in the studied amphipods, with oleic and palmitic acid representing the main fatty acid components. The habitat of the amphipods exerted a profound effect on their fatty acid profile: the amphipods of Gorevoy Utes contained higher levels of linolenic 18:3n3 and arachidonic 20:4n6 acids, while the amphipods of Frolikha Bay contained higher levels of eicosapentaenoic 20:5n3 and docosahexaenoic 22:6n3 acid. Based on these findings, we suggest that the amphipods’ diet in different areas of Lake Baikal determines their fatty acid composition.
