It is a polyol , a compound that is made up of more than one hydroxyl group. Glycerol can be trinitrated by reaction with concentrated nitric acid using concentrated sulfuric acid as the catalyst. 1. nonionic • fatty acid esters, such as glycerol monostearate (GMS) and more particularly ‘high-mono GMS’ containing more than 95% monoester; GMS is in accordance with most food contact regulations. KEY TERMS. Functional Groups are the substituent atoms or group of atoms that attach to a molecule and enable them to participate in specific chemical reactions. This is because each functional group contains certain bonds, and these bonds always show up in the same places in the IR spectrum. Why? Equation of the esterification of glycerol and three ethanoic acids. Glycerolipids are composed of glycerol and fatty acids. 4. Glycerol: Glycerol contains three hydroxyl groups. Molecular Weight 274.40 . Which reaction is involved in preparing margarine from corn oil? Common antistatic agents may be. According to present concepts, glycerol phosphate derived from glucose is utilized for GPL biosynthesis in cancer cells (18, 19). It is a member of the major intrinsic protein (MIP) family of transmembrane channel proteins.
