Fatty acids of liver, carcass, and milk of rats fed corn oil, rapeseed oil, partially hydrogenated herring oil, or margarine were examined by gas–liquid chromatography. Appreciable quantities of linoleic acid were maintained in the tissues and milk, even when the hydrogenated herring oil with a low level of linoleic acid was fed. The proportion of C20and C22acids deposited or secreted was related to that of the diet, and was highest with rapeseed oil. In the livers of rats fed each diet, long-chain, polyunsaturated acids were observed. The fatty acids of milk more closely reflected the dietary pattern than did those of the tissues.

Proximate Analyses

Anethum sowa L. (Dill) seeds were investigated to determine the fatty acid composition and proximate analyses. The seeds contain 9.36 % fatty oil. The saturated and unsaturated fatty acids contributed 6.22% and 93.78% respectively of the oil. The per cent composition of the extracted oil was identified by Gas Liquid Chromatography (GLC). Among the six fatty acids identified from this study oleic acid contributed the highest proportion (87.10%), where as, linolenic, palmitic, stearic, behenic and arachidic all together contributed the rest (12.90%). Proximate analyses showed that A. sowa. seeds are good source of dietary fibre. Overall Dill seeds oil can be considered as a good source of oleic acid.

The total saponifiable fatty acids of three stable L-phase variants of Staphylococcus aureus induced by cycloserine, methicillin, and lysostaphin were examined by gas-liquid chromatography. Five separate preparations of each of the three variants were examined. Twenty-nine fatty acids were identified. The fatty acid patterns of the three variants were very similar.

Long Chain

The fatty acid composition of 20 species of marine animals, primarily fishes and crustaceans, was determined by gas–liquid chromatography. The species came from various depths down to 4400 m. The results showed that the medium-chain saturated and the long-chain polyunsaturated acids decreased with increasing depth, while oleic acid increased. It was thought that this indicated the presence of large amounts of wax esters. A benthic, mud-feeding holothurian Scoloplanes theeli was shown to have a fatty acid composition markedly different from that of pelagic species. This was attributed in part to the bacterial components of its diet.

Fatty Acid Compositions

The fatty acid compositions of liver, skin, abdominal fat, and residual degutted carcass from each of five rats fed diets containing corn or rapeseed oil for 21 weeks were determined by gas-liquid chromatography. Statistical analysis of the results showed no significant variations among rats or among cutaneous, abdominal, and carcass fats. In these fat depots, the proportions of fatty acids resembled those of the diet except for palmitic, palmitoleic, oleic, and erucic acids. Glyceride compositions of the body fats were in agreement with those predicted by Vander Wal's distribution theory.

Methyl Myristate

Calves were fed from 5 to 85 days of age a synthetic milk that contained either 10% corn oil (ca. 50% linoleic acid) or 10% methyl myristate. The fatty acid composition of almost all tissues studied was altered to some extent by the change in dietary fatty acids. In the central nervous system, the medulla and spinal cord were resistant, but the peripheral nervous system (sympathetic trunk, brachial plexus, and vagus nerve) profoundly reflected alteration in dietary fatty acids. In peripheral nervous tissue from calves fed corn oil the proportion of linoleic acid increased from 2 to 5% to 25 to 30%. Similarly, in such tissues, myristic acid increased from 2 to 6% to 16 to 43% in methyl myristate-fed calves. Even the fatty acid composition of endocrine glands (pituitary, adrenal, and testis) reflected dietary fatty acids. The fatty acid composition of the skeletal muscle, adipose tissue, and aorta changed with different dietary fats. The greatest change occurred in the cardiac muscle and liver, in which the proportion of linoleic acid increased in the corn oil-fed calves to 50% of the total fatty acids.

SummaryAs determined by gas-liquid chromatography, the mean fatty acid composition (weight percentages of total fatty acids) of milk fat from sows fed a diet to meet U.S. N.R.C. nutrient requirements was: oleic, 35·3; palmitic, 30·3; linoleic, 13·0; palmitoleic, 9·9; stearic, 4·0; myristic, 3·3; linolenic, 2·5; unidentified 0·7 and 0·5, presumably n-odd chain and branched fatty acids; lauric, 0·3; and capric, 0·2. The corresponding fatty acid composition of colostrum fat was: oleic, 41·7; palmitic, 22·5; linoleic, 20·9; palmitoleic, 5·0; stearic, 5·7; myristic, 1·4; linolenic, 2·4; and unidentified acids, 0·3 and 0·1. Dietary fat increased fat levels in the milk and influenced fatty acid composition of the milk fat. Backfat resembled colostrum fat more than milk fat.

Abstract The influence of the type of dietary fat on the effects of thyroid hormones was investigated in mice. Hyperthyroidism was achieved by providing thyroid hormones (T3 and T4) in the drinking water. Both hyperthyroid and euthyroid mice (Mus musculus) were fed isoenergetic diets containing 18% (w/w) total lipid but differing in fatty acid composition. Diets were either low in the polyunsaturated linoleic acid (18:2, ω6) and high in saturated fatty acids (SFAs) or low in saturated fats and high in the polyunsaturated fatty acid (PUFA), linoleic acid. Treatments were maintained for 21–22 days. Plasma thyroid hormone levels, standard metabolic rate (SMR), changes in body mass, specific activities of malic enzyme (ME), Na-K-ATPase and glycerolphosphate dehydrogenase (GPDH) of the liver were measured. Fatty acid composition of the liver phospholipids was also determined. Levels of T3 (15–17 nm) and T4 (250–255 nm) were significantly higher in the respective hyperthyroid groups. There was no significant influence of the diet on hormone levels. Hyperthyroidism increased the SMR 37–44% above the euthyroid levels. A significant body weight loss of 14–18% was observed in hyperthyroid mice on the PUFA diet but not in those on the SFA diet. PUFA diet significantly reduced the activity of ME but had no effect on Na-K-ATPase or GPDH activity. Activities of Na-K-ATPase and GPDH were significantly elevated in all hyperthyroid groups. Mice on T4 and PUFA diet showed a highly significant 399% increase in GPDH activity above the euthyroid level. The overall degree of unsaturation of the fatty acids in the liver phospholipids was comparable in all groups. Dietary treatment substantially changed liver membrane fatty acid composition whilst hyperthyroidism resulted in only small changes. The only parameters to show an interaction between dietary fat profile and hyperthyroidism were ME activity, changes in body mass and liver phospholipid fatty acid composition.

Fatty Acid Patterns

SUMMARY The fatty acid patterns of the cholesterol ester, triglyceride and phospholipid fractions of serum from thirteen hypothyroid subjects have been determined using gas-liquid chromatography. A comparison was made with the results of similar analyses performed on sixteen apparently normal subjects and on eighteen patients with ischaemic heart disease. A trend towards increasing saturation was found in each of the fractions from the hypothyroid subjects. This was most marked in the cholesterol esters. The mechanism of the production of this trend is discussed and it is suggested that it is secondary to the hyperlipidaemia of hypothyroidism. Attention is drawn to the implication of these findings in interpreting the reported changes in the fatty acid composition of the serum lipids in atherosclerosis.

Fatty acid composition of Nyctanthes arbortristis Linn root extracted successively  with light petroleum ether (40-600C bp.)- n-hexane and chloroform were analyzed by gas liquid chromatography (GLC). Twenty one fatty acids were identified in the Seuli root. The major saturated and unsaturated fatty acids are palmitic acid (C16:0, 13.97%) and oleic acid (C18:1, 28.43%). Physio-chemical characteristics, such as iodine value, moisture, ash, lignin and crude fibre of the Seuli root were also determined.   Keywords: Nyctanthes arbortristis Linn; Seuli; root; fatty acid composition; gas liquid chromatography.
