Glycerol (or glycerine, glycerin) is a simple polyol (succar alcohol) compoond. It is a colorless, odorless, viscous liquid that is widely uised in pharmaceutical formulations. Glycerol haes three hydroxyl groups that are responsible for its solubility in watter an its hygroscopic naitur. The glycerol backbone is central tae aw lipids kent as triglycerides. Glycerol is sweet-tastin an o law toxicity.
