The contents of crude fat were remarkably different according to parts in porcine tissues. The most contents of total lipids in variety tissues were neutral lipid, and the nexts were phospholipid and glycolipid, where these of the most composition in liver were phospholipid and the next neutrallipid and glycolipid. The major component of the nonpolar lipids in fresh was triglyceried(58.09∼74.68%) and phospolipid in the polar lipid were phosphatidyl choline(20.14∼45.17%) and phosphatidyl ethanolamine(18.5∼30.14%) and the main component in glycolipid acylsterol glyceride(26.10∼45.15%), respectively.

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.

The lipid compositions including fatty acid sterol lipid class and the lipid component of the total lipid extracted from the flesh of some fresh water fishes I. e. mandarin cornet cat fish and Korean perch were compared. The levels of total lipid of flesh tissues from the fresh water fishes were high(7.4%) in cat fish but low(1.4-2.2%) in mandarin fish Korean perch and cornet fish. On the contrary the content of unsaponifiable matters found in total lipid was low(2.6%) in cat fish but high(6.0%-6.5%) in mandarin fish Korean perch and cornet fish. Total lipids were mainly composed of triglyceride(74.6-86.5%) as major component in each sample and the other lipid components of total lipid e. g. polar lipid free fatty acids and free sterol were the minor components, The major fatty acids in total lipid of each sample were{{{{ {C }_{16 { }:_{ }0 } }}}}(19.6-29.2%) {{{{ {C }_{16 { }:_{ }1 } }}}}(17.3-30.7%) and {{{{ {C }_{18 { }:_{ }1 } }}}}(16.8-29.2%) and additionally it chiefly consisted of {{{{ {C }_{14 { }:_{ }0 } }}}} and {{{{ {C }_{18 { }:_{ }2 } }}}} Particularly the contents of polyenoic acids in total lipid of cat fish were higher than those of the other fish samples. The level of cholesterol in total lipid was low (8.3mg/g) in cat fish but were high(36.9-59.9mg/g) in mandarin fish Korean perch and cornet fish. The contents of fractionated neutral lipid(NL) were higher than those of polar lipid(PL) in each sample. Particularly phospholipid content in PL was low(6.0%) in cat fish but were high(23.1-36.3%) in mandarin fish Korean perch and cornet fish. Neutral lipids were mainly consisted of triglyceride(84.5-93.4%) as amjor component in each sample and the other lipid components of neutral lipid e, g, free fatty acids and free wterol were exhibited as a minor components, The fatty acid compositon of neutral lipids was very resembled to total lipids. The phospholipid in mandarin cornet and cat-fish were mainly composed of phosphatidyl serine(23.1-49.8%) and phosphatidyl choline(20.8-45.3%) The relatively higher amounts of phosphatidyl serine were observed in mandarine cornet and cat-fist than in Korean perch, But phosphatidyl ethanolamine(42.3%) and phosphatidyl choline (49.9%) were the main phospholipid in Korean perch. The extraordinary high content of phos-phatidyl ethanolamine compared to other fishes was characteristics in phospholipid composition of Korean perch. The major fatty acids in phospholipid of each sample were {{{{ {C }_{16 { }:_{ }0 } }}}} (38.3-46.5%) {{{{ {C}_{18 { }:_{ }0 } }}}}(14.2-21.7) and C16:1(11.6-13.8%) and additionally it chiefly consisted of C18:2, C18:0 and C17:0 The major fatty acids in glycolipid of each sample were C16:0(28.8-40.1%) C18:1(5.4-29.9%) C18:0(5.1-28.9%) and C16:1(8.2-20.1%) and additio-nally it chiefly consisted of C14:0 and C20:1.

$28^{\circ}C$에서 자란 $3{\sim}4$엽기 벼잎조직의 인지질지방산분석을 통해 벼품종별 상대적내냉성정도와 인지질지방산조성간에 성립되는 밀접한 상관관계를 확인하였다. 즉 내냉성이 강한 품종일수록 불포화도 및 불포화지방산의 구성비가 노은 인지질을 함유하고 있다. 인지질의 불포화상태를 나타내는 모든 지표들이 각품종의 냉해저항성과 잘 일치된다는 사실은, 곧 식물세포가 저온에서 생체막과 관련된 생리적활성을 유지하는데 있어서 필수조건으로 알려진 '생체막의 유동성'은 인지질지방산조성에 의해 절대적으로 지배받는다는 것을 분명히 나타낸다. 한편 벼의 인지질은 최소한 유묘기의 잎에서는 모든 품종에서 공히 phosphatidyl serine과 phosphatidyl choline을 주성분으로 phosphatidyl inositol을 부성분으로, 그밖에 3종의 미량성분을 포함하고 있으며, 인지질의 종류 및 조성은 내냉성과 무관한 것으로 판단된다.

The organization of phospholipid monolayers on a water surface was investigated by means of Maxwell-Displacement-Current(MDC)-Measuring technique. The phase transition from the gaseous phase to the gaseous-fluid phase which accompanies the polar ordering of lipid molecules was detected by the technique in the range of immeasurable low surface pressure and the molcular-area which gives the onset of the transition was determined for lipid monolayers. The vertical component of dipole moment of lipid membranes was determined from the charge flowing the rough the circuit, and we measured differential themal analysis of sample.

This study was designed to obseve the effect of defatted perilla as a dietary fiber on lipid components of serum feces and liver in rats. Serum cholesterol and triglyceride were signfican-ly decreased in defatty perilla added groups. total lipid cholesterol and triglyceride of feces were significantly increased in defatted perilla added groups. Liver phospholipid content was higher in the defatted perilla added groups. The other lipid components of the liver were not affected by the defatted perilla administration. These results suggest the possibitlity that defatted perilla have a reducing effect of serum cholesterol and triglyceride through the incre-ment of feacal excretion of lipid component and phospholipid in liver.

The oxidation rate of krill lipids is very slow and no peroxides are accumulated even after long storage. By means of various chromatographic techniques and mass spectrophotometry, the primary antioxidant has been identified as ${\alpha}$-tocopherol. The phospholipid fractions did not show any antioxidative activity but peroxide-decomposing properties of total lipids depended upon the phospholipid contents. The peroxide-decomposing activities of phospholipids were due to the presence of polar materials generated during the storage. The most peroxide-decomposing fractions of oxidized krill lecithin by DEAE-cellulose column chromatography was low-molecule fraction (mean molecular weight: 182) and high-molecule fraction (mean molecular weight: 1942) was the next. The separation of peroxide-decomposing properties from low-molecule fraction was achieved by partitioning between chloroform and methanol/water. The methanol/water fraction showed strong peroxide-decomposing activities and main component of this fraction was assumed hydroxyamine compounds derived from choline.
