| Glycerol is a chemical compound also commonly called glycerin or glycerine. It is a colorless, odorless, viscous liquid that is widely used in pharmaceutical formulations. Glycerol is a sugar alcohol, and 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 64.00mN/m at 20C, and it has a temperature coefficient of -0.0598mN/(mK). The glycerol substructure is a central component of many lipids. Glycerol is used both in sample preparation and gel formation for polyacrylamide gel electrophoresis. Glycerol (5-10%) increases the density of a sample so that the sample will layer at the bottom of a gels sample well. Glycerol is also used to aid in casting gradient gels and as a protein stabilizer and storage buffer component.
