The fatty acid composition of human depot fat

Abstract

Early studies of human depot fat were limited by available analytical techniques and investigations into the fatty acid composition of the depot fat did not begin until about 1925. Eckstein (1925) reported 1% of myristic acid and traces of lauric acid, 26% of saturated and 63.6% of unsaturated acid, and 0 5, 0 03 and 0.33% of acids with two, three and four double bonds respectively. The dienes and tetraenes, but not the trienes, were confirmed by Wagner (1926), and 60% of unsaturated acids and 25 8-31 % of saturated acids were found by Telfer (1928) and McAmis & Anderson (1930). Cramer & Brown (1943) published the results of analyses made by fractional distillation of the methyl esters of fatty acids from depot fat, together with their new technique of low-temperature crystallization. These authors were the first to report the presence of mono-unsaturated C14 and

Esterification of free fatty acids by subcellular preparations of rat adipose tissue

“…Certain fatty acids, bowever, tend to present a degree of selectivity in some species. In fats of beer, horse, and sheep, saturated fatty acide are pre.f'erentially distrib- band, adipose tissue seems to be quite homogenous and only few minor differences, i f an;r, are noted from one site to another (29,38,47).…”

Gc-MS Analysis and Antimicrobial Activity of Fixed Oil From Sudanese Peganum Harmala L. (Zygophyllaceae).

“…The EI mass spectrum of 9-octadecenoic acid methyl ester is shown in Fig. 2.The peak at m/z 296, which appeared at R.T. 17 + .The peak at m/z266 is due to loss of a methoxyl function.…”

Serum Metabolomics in Rats after Acute Paraquat Poisoning

“…In humans, one analysis found it to comprise 21-30% (molar) of human depot fat. 19) Hexadecanoic acid negatively feeds back on acetyl-CoA carboxylase (ACC), which is responsible for converting acetyl-CoA to malonyl-CoA, which in turn is used to add to the growing acyl chain, thus preventing further palmitate generation.…”
