Glycerol hydroxyl group
WebGlycerol and Fatty Acids. One major class of lipids is called glycerolipids. Glycerolipids are composed of glycerol and fatty acids. Glycerol, whose structural formula is shown at right, has three carbon atoms, each of which has a hydroxyl (-OH) group bound to it.. Fatty acids are fairly long linear hydrocarbon chains with a carboxylic acid group at one end. WebDec 29, 2024 · Glycerin is a by-product of soap production. It is humectant meaning it helps skin and hair retain moisture. It is ideal for water-based formulations as it readily dissolves in water. It is also used as a preservative for preserving delicate items. Glycerin is a simple polyol – having simple hydroxyl groups in its chemical structure.
