Detailed explanation-1: -Answer. A phospholipid is a type of compound lipid made of a phosphate group, a glycerol molecule, and two fatty acid chains. Fatty acids are molecules made of a carboxyl group attached to a long, hydrocarbon chain.
Detailed explanation-2: -Fatty acids are merely carboxylic acids with long hydrocarbon chains. The hydrocarbon chain length may vary from 10-30 carbons (most usual is 12-18). The non-polar hydrocarbon alkane chain is an important counter balance to the polar acid functional group.
Detailed explanation-3: -Triacylglycerols Structure and Functions Fatty acids and glycerol are the building blocks of triacylglycerols. Glycerol is a thick, smooth, syrupy compound that is often used in the food industry. To form a triacylglycerol, a glycerol molecule is joined by three fatty acid chains.
