Glyceride biosynthesis

In order to investigate whether the above glycerides are derived from the animal s diet or by biosynthesis, [2-14C]RS-mevalonic add DBED salt was injected into the digestive gland of A. montereyensis and A. odhneri spedmens, which were placed in a running sea-water aquarium for 24 h and then extracted [79]. Incorporation of the label was checked in the major metabolites of the two nudibranchs, namely 23 and 51 in A. montereyensis and 47 in A. odhneri, after HPLC purification and conversion to derivatives that were also purified via...

Fats and fat-like compounds of varying chemical structures are classified as lipids. They have a low molecular weight and are insoluble in water. The original substance in fat biosynthesis is acetyl-CoA (so-called activated acetic acid). On the basis of chemical criteria, they may be divided into simple lipids (glycerides, cholesterol, cholesterol esters, bile acids) and complex lipids, (s. tab. 3.7)...

Lipases degrade glycerides to glycerol and free fatty acids. Diacylglycerols in the free or phosphorylated form (phosphatidic acids) are precursors of groups of phospholipids that are important membrane constituents (Table 27). In the biosynthesis of these compounds the following reactions are of significance ... 

It has long been recognized that the biosynthesis of glycerides occurs via the intermediate formation of complex lipids. 

The plasmalogenic diglyceride, prepared enzymically by the action of phospholipase C on the choline-containing phospholipid of beef heart, is defined as a D-a,/5-diglyceride in which the ester at the cx -position is replaced by an imsaturated ether. The reaction is catalysed by a choline-phosphotransferase enzyme similar to the phosphorylcholine-glyceride transferase shown to participate in the biosynthesis of lecithin (Reaction 12). A similar reaction occurs in brain (McMurray 1964b).
