In chemistry, a triol is an organic compound containing three hydroxyl groups (−OH functional groups), such as glycerol.
In chemistry, a triol is an organic compound containing three hydroxyl groups (−OH functional groups), such as glycerol.
In organic chemistry, a polyol is an organic compound containing multiple hydroxyl groups (−OH). The term "polyol" can have slightly different meanings depending on whether it is used in food science or polymer chemistry. Polyols containing two, three and four hydroxyl groups are diols, triols, and tetrols, respectively.
Glycerol (/ˈɡlɪsərɒl/) is an organic compound with chemical formula C3H5(OH)3. It has a three-carbon backbone and is a simple triol compound (an alcohol with three hydroxyl groups). It is a colorless, odorless, sweet-tasting, viscous liquid. Because of its three hydroxyl groups, glycerol is miscible with water and is hygroscopic in nature.
The glycerol backbone is found in lipids known as glycerides, where one or more of the hydroxyl groups are esterified with fatty acids. The most abundant of glycerides are triglycerides (found in animal fats and vegetable oils), it is where glycerol is most commonly found in nature. It is also widely used as a sweetener in the food industry and as a humectant in pharmaceutical formulations.
