Detailed explanation-1: -Glycerol has a polar hydroxyl group for every carbon atom and thus it is soluble in water so it is not a lipid it is simple alcohol.
Detailed explanation-2: -They include gastric lipase, colipase-dependent pancreatic lipase, pancreatic lipase-related proteins 2 (PLRP2), carboxyl ester hydrolase or bile salt-stimulated lipase (CEH, BSSL), and pancreatic phospholipase A2.
Detailed explanation-3: -Key enzymes that are involved in regulation of lipid metabolism are carnitine palmitoyltransferase 1, acetyl-coA carboxylase, fatty acid synthase, and 3-hydroxy-3-methyl-glutaryl coenzyme A reductase. Carnitine palmitoyltransferase 1 transfers fatty acid into the mitochondria for oxidation.
Detailed explanation-4: -Arachidonic acid is a fatty acid with 20 carbon atoms. It is not a derived lipid.
