The lipolytic hypothesis of fat absorption advocated by Verzar and McDougall7 in 1936 maintains: that ingested fat undergoes emulsification to soap and complete hydrolysis to fatty acid and glycerol in the small intestine; that a solid pavement epithelial structure exists on the intestinal mucosal cells; that the fatty acids pass through the membrane as soluble complexes with bile salts, while ...

It has been shown by several workers that fatty acids liberated by the hydrolyses of their esters, such as amyl (I), ethyl (2), or the optically active mannite (3), appear in the thoracic duct chyle as triglycerides. In comparing the absorption of free palmitic acid and some of its esters, Lyman (4) found that in each case the fat deposited in the tissues was tripalmitin. It was assumed, theref...

Recyclable and reusable heterogeneous diarylammonium catalysts are highly effective in catalyzing the esterification of the free fatty acid (FFA) present in greases to methyl esters to reduce the FFA content from 12-40 wt% to 0.5-1 wt%; the resulting ester-glyceride mixture (pretreated grease) could then be readily converted to methyl esters by base-catalyzed transesterification.

Glycerol monolaurate (GML), a representative fatty acid glyceride, was used to promote growth. This study investigated the effects of GML in diets on growth, serum biochemical parameters, antioxidant capacity, liver morphology and lipid metabolism for juvenile pompano Trachinotus ovatus . Six groups T. (mean weight = 14.00 ± 0.70 g) were fed with six diets, containing varying levels 0.00% (G0),...
