Glycerol vs. Glycine: Know the Difference

By Shumaila Saeed || Updated on December 25, 2023

Glycerol is a simple polyol compound used as a sweetener and in pharmaceuticals, while glycine is the simplest amino acid, involved in protein synthesis.

Glycerol vs. Glycine

Key Differences

Glycerol, a trihydroxy alcohol, is a viscous liquid often used in food and pharmaceuticals. Glycine, on the other hand, is a non-essential amino acid, the simplest in the human body.

Dec 06, 2023

Glycerol is a backbone for triglycerides and an important intermediate in carbohydrate and lipid metabolism. Glycine plays a critical role in the synthesis of proteins, purines, and other amino acids.

Dec 06, 2023

Glycerol is sweet-tasting, colorless, and odorless, used in food, cosmetics, and as a moisturizer. Glycine is a sweet-tasting, colorless, crystalline solid, used in dietary supplements and as a flavor enhancer.

Dec 06, 2023

Glycerol is used in the production of nitroglycerin, antifreeze, and as a plasticizer. Glycine is used in antacids, analgesics, and for therapeutic purposes in neurology and psychiatry.

Dec 06, 2023

Glycerol, with three hydroxyl groups, is highly reactive in forming esters and ethers. Glycine, with a single hydrogen as its side chain, is the only achiral amino acid and is less reactive.
