GENERAL DESCRIPTION |
||
| Glutaric acid (Pentanedioic Acid)is a dicarboxylic acid with five carbon atoms, occurring in plant and animal tissues. Glutaric acid is found in the blood and urine. Alpha-ketoglutaric acid, a derivative of glutaric acid which has a ketone group on the carbon atom next to the acid group, is produced from glutamate in amino group and found as an intermediate in the Krebs cycle in the body. In industrial field, ketoglutaric acid exhibits typical carboxyl group chemistry useful in a variety of industrial applications. It is a white crystalline solid having has the lowest melting point among dicarboxylic acids (98 C). It is very soluble in water and the solution is a medium strong acid. The molecular structure of odd carbon number is also useful to decrease polymer elasticity. Glutaric acid is used in the production of polyester polyols, polyamides, ester plasticizers and corrosion inhibitors. It is used in the synthesis of pharmaceuticals, surfactants and metal finishing compounds. Food grade alpha-ketoglutaric acid is used in dietary supplements to improve protein synthesis. | ||
