Major Saturated Fatty Acid

Fatty acid composition of the muscle lipids of Carassius gibelio, Pseudophoxinus anatolicus, Sander lucioperca, Tinca tinca, Vimba vimba tenella and Capoeta capoeta in Sugla Lake were determined. In all species, palmitic acid (13.25- 18.54% of total fatty acids) and oleic acid (11.93-34.23% of total fatty acids) were identified as major saturated fatty acid (SFA) and monounsaturated fatty acid (MUFA), respectively. Docosahexaenoic acid (DHA) was found to be the major polyunsaturated fatty acid (PUFA) in T. tinca, C. capoeta, C. gibelio, P. anatolicus and S. lucioperca while the predominant PUFA of V. vimba tenella was eicosapentaenoic acid (EPA). S. lucioperca contained more ?3 fatty acids than the other fish species. The percentages of total ?3 fatty acids were higher than those of total ?6 fatty acids in all species. Since P. anatolicus is endemic and endangered, this species should be protected and produced for future marketing.

Oleic acid was the highest monounsaturated fatty acid (MUFAs) inCyprinus carpio(Işıklı Dam Lake) (19.25%). The most abundant polyunsaturated fatty acid inScardinius erythrophthalmuswas docosahexaenoic acid (DHA) (17.94%).

Samples of the infaunal invertebrates Nephtys incisa and Yoldia limatula from Narragansett Bay, Rhode Island, have been analyzed for their fatty acid distribution. Based on total fatty acids, Yoldia contains 9–16% of an acid tentatively identified as 22:2. The ratios of 18:1/18:0 and 18:1/20:1 fatty acids of Nephtys from a polluted station in the bay are lower than the corresponding ratios for animals from relatively clean areas.

The aim of the present study was to characterize the effects of feeding tuna oil on the lipid and fatty acid composition of boar spermatozoa and to relate changes in composition to boar semen characteristics. Ten boars were paired by age and allocated to one of two diets (five boars per diet). The diets, which were offered for 6 weeks, consisted of a basal diet that was either unsupplemented or supplemented with 30 g tuna oil kg(-1) diet. Adding tuna oil to the diet increased the ether extract concentration of the diets fed from 65 to 92 g kg(-1) dry matter and supplied 10.5 g long chain polyunsaturated (n-3) fatty acids per 100 g total fatty acids. There were no changes in semen fatty acid composition after 3 weeks of feeding tuna oil. However, after 5 and 6 weeks, the proportions (g per 100 g total fatty acids) of 22:6(n-3) in sperm phospholipid fatty acids were increased from 34.5 to 42.9 g by feeding tuna oil and 22:5(n-6) decreased from 29.8 to 17.9 g. No changes were observed in other sperm lipids or seminal plasma phospholipids as a result of the diets fed. Feeding tuna oil increased the proportion of spermatozoa with progressive motility and with a normal acrosome score and reduced the proportion of spermatozoa with abnormal morphologies.

Abstract Chloroplasts isolated from three populations of the tropical marine Chlorophyte Anadyomene stellata collected off the coast of Greece were analyzed for their fatty acid composition. Following the preparation of fatty acid methyl esters, GC-MS (El) was utilized to identify the fatty acids present in each population. Including isomers, the fatty acid profile of all three algal populations was comprised of 19 fatty acids (4 saturated, 6 monounsaturated, 9 polyunsaturated) with palmitic acid present in the highest amounts (25-27% of total fatty acids). Analysis of variance revealed significant differences amongst the three populations in the percent of total fatty acids for twelve of the fatty acids. High levels of C20 PUFAs, an atypical observation in Chlorophytes, were observed in all three populations comprising approximately 17% of total fatty acids. Furthermore a 14:2 PUFA , apparently rare in marine macrophytic Chlorophytes, was identified in significant quantities. Surprisingly, we did not find any of the conjugated tetraene containing fatty acids that we previously identified in the A. stellata populations studied from the Florida Keys.

Representative samples of channel catfish (Ictalurus punctatus Rafinesque) were obtained from five processing plants and analyzed by gas–liquid chromatography for fatty acid composition of muscle tissues. Twenty-three fatty acids were measured. The saturated fatty acids comprised 26.5%, monoenes 48.1%, dienes 13.0%, trienes 3.1%, tetraenes 3.6%, pentaenes 1.3%, and hexaenes 1.9% of total fatty acids. Fatty acid composition varied significantly (P <.01) among fish obtained from the same plant, and in addition, significant variation associated with processing plant was observed for some fatty acids.

Background: Fishes are good sources of the fatty acids such as ω-3 and ω-6 polyunsaturated fatty acids, and fat-soluble vitamins for human consumption which play vital roles for various biological processes in the body and help in the proper growth and prevention of diseases. Objective: The objective of the present study was to determine the fatty acid composition, cholesterols, triglyceride and vitamin contents of some selected fishes from Hel river, Assam, India. Methods: Fatty acid composition of fish species was examined using gas chromatography-mass spectrometry, lipid components were determined following the reported methods and vitamins A and D contents were investigated by reversed-phase high-performance liquid chromatography. Results: Fatty acid compositions varied from 51.20-89.47% of saturated fatty acids, 0.27-19.68% of monounsaturated fatty acids and 1.75-30.76% of polyunsaturated fatty acids. Eicosapentaenoic acid and docosahexaenoic acid ranged from 0.54-22.30% and 1.26-18.85%, respectively. The fish species showed varying amounts of lipid components. The vitamins A and D were found in the range of 15.85-1287.0 μg/100 g and 45.0-677.24 μg/100 g, respectively. Conclusion: The fish species of this study are found rich in ω-3 polyunsaturated fatty acids such as eicosapentaenoic acid and docosahexaenoic acid along with noticeable amounts of vitamins A and D. Hence, these fish species have the potentials to serve as the natural dietary supplements for ω-3 fatty acids and other nutrients.

This study investigated protein, amino acid, fatty acid composition, in vitro starch and protein digestibility, and phenolic and antioxidant composition of bread fortified with salmon fish (Oncorhynchus tschawytscha) powder (SFP). The proximate composition in control and SFP breads ranged between (34.00 ± 0.55–31.42 ± 0.73%) moisture, (13.91 ± 0.19–20.04 ± 0.10%) protein, (3.86 ± 0.02–9.13 ± 0.02%) fat, (2.13 ± 0.02–2.42 ± 0.09%) ash, (80.10 ± 0.018–68.42 ± 0.11%) carbohydrate, and (410.8 ± 0.18–435.96 ± 0.36 kcal) energy. The essential amino acids of the control and SFP breads ranged between 261.75 ± 9.23 and 306.96 ± 6.76 mg/g protein, which satisfies the score recommended by FAO/WHO/UNU (2007). Protein digestibility of the products was assessed using an in vitro assay. The protein digestibility, comma, amino acid score, essential amino acid index, biological value, and nutritional index ranged between 79.96 ± 0.65–80.80 ± 0.99%, 0.15 ± 0.06–0.42 ± 0.06%, 62.51 ± 1.15–76.68 ± 1.40%, 56.44 ± 1.05–71.68 ± 1.10%, 8.69 ± 0.10–15.36 ± 0.21%, respectively. Control and SFP breads contained 60.31 ± 0.21–43.60 ± 0.35 g/100 g total fatty acids (saturated fatty acids) and 13.51 ± 0.10–17.00 ± 0.09 g/100 g total fatty acids (polyunsaturated fatty acids), and SFP breads fulfil the ω-6/ω-3 score recommended by food authority. There was a significant effect of SFP on bread-specific volume, crumb color, and textural properties. The in vitro starch digestibility results illustrate that the incorporation of SFP into wheat bread decreased the potential glycemic response of bread and increased the antioxidant capacity of bread. In conclusion, this nutrient-rich SFP bread has the potential to be a technological alternative for the food industry.
