Explanation: 

Detailed explanation-1: -glycerol contains three hydroxyl groups in its chemical structure, which are-OH groups bound to the carbon atoms. It has 3 Carbon atoms, 3 Oxygen atoms, and 8 Hydrogen atoms.

Detailed explanation-2: -Glycerin is a polyol compound that contains three hydroxyl groups and three carbon atoms.

Detailed explanation-3: -Glycerol is an alcohol with three carbons, five hydrogens, and three hydroxyl (OH) groups. Fatty acids have a long chain of hydrocarbons with a carboxyl group attached and may have 4-36 carbons; however, most of them have 12-18.
