A highly purified lipase was prepared from the particulate fraction of rat adipose tissue. Although the lipase catalyzes the hydrolysis of diglycerides and triglycerides of both long and short chain fatty acids, monoglycerides are not hydrolyzed. The enzyme has a marked specificity toward fatty acids esterified to the primary hydroxyl groups and hydrolyzes a,-diglycerides 10 times more rapidly ...

As for saturated and monounsaturated fatty acids, the omega-6 and omega-3 polyunsaturated fatty acids (PUFA) are chemically linked to fat structures known as triglycerides in the various foods and oils that are consumed. The natural triglyceride or fat structure consists of a 3-carbon glycerol backbone onto which 3 long-chain fatty acids of varying types and structures are linked or 'esterified...

Consistent with its central importance in lipid and energy homeostasis, lipolysis occurs in essentially all tissues and cell types, including macrophages. The hydrolytic cleavage of triacylglycerol by adipose triglyceride lipase (ATGL) generates non-esterified fatty acids, which are subsequently used as essential precursors for lipid and membrane synthesis, mediators in cell signaling processes...

Two groups of adult male rats 8 weeks old were fed a 10 p. 100 protein (casein) diet with or without 2 p. 100 methionine. After 8 rats in each group were killed at 10 a.m. on experimental days 1, 2, 4, 8 and 21, we studied the profiles of plasma non-esterified fatty acids (NEFA) and of the hepatic activities of pyruvate kinase (PK), phosphoenolpyruvate carboxykinase (PEPCK), glucose-6-phosphate...

Material and methods Multiparous cows (n=74) at the Swedish Livestock Research Centre Lövsta, with BCS from 2 to 4.25 the first week PP were enrolled. Insulin, non-esterified fatty acids (NEFA), glucose and insulin like growth factor 1 was determined week two PP. The Revised Quantitative Insulin Sensitivity Check Index (RQUICKI) was used to estimate IS. Progesterone in milk was determined twice...

The fatty acid composition of liver mitochondrial phospholipids from rats rendered deficient in essential unsaturated fatty acids has been determined, and compared with that of rats fed a diet containing corn oil. In addition to marked reductions in the amounts of linoleic and arachidonic acids esterified a t the &position of ethanolamine-, inositol-, and choline glycerophosphatides, the defici...

This paper reports the composition of total fatty acids in an apple beverage, cider. Fatty acids are present in the free or esterified form and contribute to both the flavor and foam properties of cider. Fatty acids were separated and identified as methyl esters by GC-MS, and 12 of these were subsequently determined by GC-FID. The major fatty acids found in cider were caproic, caprylic, capric,...
