The fatty acid composition of muscle were investigated to compare muscle composition among the 9 domestic animals including cattle. In major domestic animals, analyzed the effects of age, part and sex of the animal on their fatty acid composition. The content of 4 types of major fatty acids of muscle was determined and calculated their ratio. Myristic acid and palmitic acid levels were high in chicken and sheep. Besides dog muscle contained a lot of stearic acid. Linoleic acid content showed evident difference in the content depending on the animal species. The ratios of linoleic acid/palmitic acid (L/P ratio) and linoleic acid/stearic acid(L/S ratio) were characteristically high in horse and pig, whereas the ratio of palmitic acid/stearic acid(P/S ratio) was $0.71{\pm}0.17$, showing very low level in dog. As for the content of stearic acid, in cattle and chicken it was higher in young animal than adults. In duck, the contents of all fatty acids and ratio were increased by the age. As for the content of fatty acids according to the part of chicken, high level was shown in thigh than in breast and wing, while there was no remarkable variation by the part in other animal. The differences in the content of myristic acid, palmitic acid and linoleic acid among some animal could be verified in muscle lipid composition. The L/P ratio which maintained certain level regardless of age, part, sex shown distinctive pattern between the species.

This study was carried out to investigate the effect of the feeding mixture of linseed oil, rich in n-6 PUFA on the lipid metabolism in the dietary hyperlipidemic rats. After male Sprague-Dawley rats were induced hyperlipidemia by feeding the diet containing lard, butter and cholesterol for 3 weeks. then they were fed with the diet containing lard 3.0% and butter 12.0% for control, the mixture in different proportion of both linseed oil and sunflower seed oil, and antihyperlipidemic drugs for 2 weeks. Analysis of the fatty acid composition of the brain and heart lipids showed following results. In the fatty acid composition of brain lipids, C20:4 and C22:6 were the major fatty acids but showed little difference among the groups. In the fatty acid of heart lipids,C18:2 was the major fatty acid. The proportion of C20:4 decreased gradually as n-3P/n-6P ratio of the test lipids increased in groups 5 (linseed oil 12.0%) to 9 (sunflower seed oil 12.0%) while the proportion of C22:6 was not affected by the fatty acid composition of the test lipids.

In this study, we determined lipid content, total fatty acid composition, trans fatty acid(tFA) content, and acid value of twenty black-bean-sauce noodles collected in Seoul city area. Total lipid contents of twenty samples were determined to be 3.33~9.23% on wet base. Total unsaturated fatty acids were from 47.83% to 83.18%(mainly oleic and linoleic acid). Total saturated fatty acids ranged from 16.06% to 51.48%. Besides, tFA contents in total lipid of samples were ranged from 0.38% to 1.39%, equivalent to 20 to 80mg per 100g of black-bean-sauce noodles. Acid values of lipids extracted from samples ranged from 0.56 to 2.88.

We assessed the effects of single-nucleotide polymorphisms (SNPs) within the porcine fatty acid synthase (FASN) gene regarding meat quality and fatty acid composition in two pig populations: Korean native pigs (KNP) were crossed with Yorkshire (YS) $F_2$, and KNP were crossed with Landrace (LR) $F_2$. Direct DNA sequencing using eight KNP and eight YS pigs revealed two SNPs: c.265C>T (silent) in exon 4 and c.6545A>C (Asn${\rightarrow}$His) in exon 39. The frequency of the two SNPs was analyzed using the polymerase chain reaction-restriction fragment length polymorphism method in seven pig breeds and their association with meat quality traits and fatty acid composition was studied. In the $KNP{\times}YSF_2$ population, both SNPs were significantly associated with the level of monounsaturated fatty acids, including palmitoleic (C16:1) and oleic acid (C18:1) (p<0.005). c.6545A>C was associated with intramuscular fat content in both populations. Our results indicate that variations in c.265C>T and c.6545A>C of the pig FASN can be used to select animals with better fatty acid composition and meat quality. Moreover, KNP was a useful breed for identifying genetic factors affecting meat quality and fatty acid composition and for producing high quality pork.

In this study, total lipid and cholesterol contents and fatty acid composition of colostrum milk obtained from 30 normal mothers, 10 mothers who was delivered of preterm infant and 8 pregnancy induced hypertensive mothers were analyzed. While total cholesterol content in preterm colostrum was significantly lower than other groups (p<0.05), total lipid content was not different among three groups, ranged 2.24-.2.2g/dl. Composition of saturated fatty acide, such as lauric acid and myristic acid which are medium chain fatty acids in preterm milk were higher than those of normal-term and hypertensive mother's milk. There was no difference n total composition of polyunsaturated fatty acids and the rationh of $\omega$6/$\omega$3 among 3 group mother's colostrum, ranged 19.45-21.45% and 6.42-7.87, respectively. but the composition of arachidonic acid and DHA in colostrum of hypertensive mothers were significantly higher than those of normal and preterm mothers. These data indicates that gestational length and complications during pregnancy may change the lipid profile and fatty acid composition of hyman milk colosstrum.

In this research, fatty acid composition and trans fatty acids of 22 selected meat products produced by Turkish companies were analyzed by capillary gas liquid chromatography (GLC). Total fat contents of the meat products ranged from 11.60-42.50%. Salami had the lowest fat content 11.60% and sucuk (soudjuk) the highest 42.50%. Major fatty acids were C$_{16:0}$, C$_{18:0}$, trans C$_{18:1}$, cis C$_{18:1}$, and C$_{18:2}$ in the samples. Total unsaturated fatty acid contents have changed from 38.73 to 70.71% of total fatty acids, and sausage had the highest percentage among the samples. The majority of samples contain trans fatty acids and the level ranged from 2.28 to 7.95% of the total fatty acids. The highest amount of total trans fatty acids was determined in kavurma (Cavurmas) (7.95%), and total trans fatty acids of meat products such as pastrami contained more than 5% of the total fatty acids.

This study was undertaken to determine the effects of fish oil supplementation with low dose on the lipid content and fatty acid composition of breast milk. Among 18 lactating women who were exclusively breast-fed their babies, 6 were in control group and 12 were in fish lil groups. The subjects in fish oil groups were supplemented with 1.96g/d or 3.92g/d of fish oil for 2 weeks from 10 to 12 weeks of postpartum. All subjects consumed their usual diet at home. Breast milk samples were collected at the final day of experiment. By fish oil supplementation, the concentrations of triglyceride, cholesterol, free fatty acid and phospholipid as well as total lipid in breast milk tended to increase, but not significant. There was no dose-dependent response. The fatty acid composition of breast milk was not changed by fish oil supplementation. These results suggest that low dose of fish oil supplementation may increase of lipid content, but does not affect on the fatty acid composition of breast milk.

This study was designed to observe the effects of the mixed diets of edible mushrooms and vegetables oils on the lipid component and fatty acid composition in liver of the diet induced hydpercholesterolemic rats. Ten groups of male S.D. rats were fed a basal diet supplemented with 5% of one of three mushrooms(G.I, L.e, A.j) and 10% of one of three vegetable oils (olive ,safflower perilla) for three weeks. In liver, total cholesterol concentration was significantly low in group 3 (olive oil 10 % + L. edodes 5%) and 6 (safflower oil 10 % $_2$L. edodes 5%) , triglyceride concentration was low in groups 8 (perilla oil 10 % + g. lucidum 5%) and 9 (perilla oil 10% + L. edodes 5%) and phospholipid concentration was significantly low in groups 3, 5, (safflower oil 10 % + G.lucidum 5%), 6, 7 (safflower oil 10 % + A .judae 5%) 8, 9 and 10 (perilla oil 10% + a. judae 5%). in the fatty acid composition of total lipid inliver, monounsaturated fatty acid (MUFA) concentration s were high in groups 2 (olive oil 105 + g. lucidum 5%), 3, and 4 (olive oil 10% + A. judae 5%) and all the perilla oil groups, polyunsaturated fatty acid (PUFA) and linoleic aicd concentrations were signifciantly high in all the safflower oil groups. In the fatty acid composition of liver phospholipid , PUFA concentrations were ghih but MUFA concentrations were low. In the triglyceride component, MUFA were some more than saturated fatty acid (SFA) . In the cholesteryl ester component, MUFa concentrations were significantly high. In the fatty acid composition of liver lipid components, linholeic acid was high in the PUFA and so it was major fatty acid. Eicosapentaenoic acid (EPA) of phospholipid component in liver was significantly high.
