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.
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.
Detailed explanation-3: -In a fat molecule, a fatty acid is attached to each of the three oxygen atoms in the –OH groups of the glycerol molecule with a covalent bond (Figure 2).
Detailed explanation-4: -Phospholipids. Phospholipids constitute another important class of lipids. These are similar to similar to trigylcerides in that they have a glycerol backbone, but there are only two fatty acids connected to glycerol.
