HUMAN NUTRITION

Detailed explanation-1: -In a fat molecule, the fatty acids are attached to each of the three carbons of the glycerol molecule with an ester bond through the oxygen atom. During the ester bond formation, three molecules are released. Since fats consist of three fatty acids and a glycerol, they are also called triacylglycerols or triglycerides.

Detailed explanation-2: -Esterification is a process in which a carbonyl group is attached with alcohol with a release of a water molecule. The bond formed between both organic molecules is called an ester linkage. A simple fatty acid monomer of a lipid consists of an even number of hydrocarbon chains joined with single bonds.

Detailed explanation-3: -Since glycerol has three alcohol functional groups, three fatty acids must react to make three ester functional groups. The three fatty acids may or may not be identical.
