The biosynthesis of triglycerides in most tissues is generally considered to occur primarily via the sn-glycerol-3-phosphate pathway.In tissues known to carry out the synthesis of triglycerides, the activity of the glycerol-3-phosphate pathway is relatively constant (Schultz and Johnston, 1971). Fats 1st broken down to F.A.s, then attach to protein carriers & carried to muscles via bloodstream; then released and undergo energy producing reactions. Actions.

In mammals, FAS contains two subunits, each containing multiple enzyme activities. Can a triacylglycerol (triglyceride) storage fat be synthesized entirely from glucose, i.e., every carbon in the fat comes from a sugar? The Neutral simple lipids are esters of glycerol and long chain fatty acids containing generally 16 or 18 carbon atoms.

Describe the structure of fatty acids and explain how saturated, monounsaturated, and polyunsaturated fatty acid structures differ from one another. The acyl group is now ready to condense with a new malonyl group to repeat the process. The overall process of triglyceride (triacylglycerol) biosynthesis consists of four biochemical pathways: fatty acyl-CoA biosynthesis, conversion of fatty acyl-CoA to phosphatidic acid, conversion of phosphatidic acid to diacylglycerol, and conversion fo diacylglycerol to triacylglycerol. In bacteria and plants, individual proteins, which associate into a large complex, catalyze the individual steps of the synthesis scheme.
