Glycerol is a chemical compound with the formula HOCH2CH(OH)CH2OH. This colorless, odorless, viscous liquid is widely used in pharmaceutical formulations. Also commonly called glycerin or glycerine, it is a sugar alcohol and fittingly is sweet-tasting and of low toxicity. Glycerol has three hydrophilic alcoholic hydroxyl groups that are responsible for its solubility in water and its hygroscopic nature. Its surface tension is 64.00 mN/m at 20 °C and it has a temperature coefficient of -0.0598 mN/(m K). It is a central component of lipids.

Glycerol remains unchanged in all lipids (fats) because lipids are made up of two chemical molecules--glycerol and fatty acids. There is always one glycerol molecule, and the number and type of fatty acid depends on what lipid it is. So the glycerol molecule maintains constant while the amount of fatty acid molecules added to the glycerol (to make a lipid) varies.

Glycerol is the molecule that remains unchanged in all fat molecules. It forms the backbone structure of triglycerides, which are the most common type of fats found in the body and in foods.
