Detailed explanation-1: -Typical natural lipase substrates include, in order of amphipathicity, long aliphatic chain acyl esters of cholesterol (cholesteryl esters), triacyl esters of glycerol (triacylglycerols), acyl esters of long chain alcohols (wax esters), diacyl esters of glycerol (diacylglycerols), and monoacyl esters of glycerol.
Detailed explanation-2: -The substrate of the lipase enzyme is the lipid. The lipase enzyme is responsible for the breakdown of the fatty acids of the triglycerides into smaller subunits that can be dissolved easily and are easily digested.
Detailed explanation-3: -Triglycerides (TGs) are the main constituent of animal fat and play an important role as transporters of fatty acids as well as serving as an energy source. TGs are broken down into fatty acids and glycerol, after which both can serve as substrates for energy producing and metabolic pathways.
Detailed explanation-4: -the substrate is the triglyceride which is the building unit of lipids, and the product is the sub-units of the triglyceride which are the glycerol and the fatty acid.
Detailed explanation-5: -Lipases catalyze the hydrolysis of ester bonds in lipid substrates and play a vital role in digestion and the transport and processing of dietary lipids substrate (Svendsen, 2000).
