Explanation:
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: -A triglyceride is formed when the three hydroxyls (OH-) groups of a single glycerol molecule react with the carboxyl group (COOH-) of three fatty acids by forming ester bonds.
