Glycerol vs triglycerides. Glycerol naturally occurring in foods and in the human body is usually joined with fatty acids and forms triglycerides, which are lipids, but again, glycerol as a standalone molecule is not a lipid but carbohydrate. When triglycerides are digested, they are broken down into glycerol and fatty acids, which are absorbed.
