| Hazard Information | Back Directory | [Uses]
2-Keto-L-gulonic Acid is used in biological studies for the formation of sorbitol metabolism by Acetobacter melanogenus. | [Definition]
ChEBI: 2-dehydro-L-idonic acid is a ketoaldonic acid. It is functionally related to a L-idonic acid and a L-gulonic acid. It is a conjugate acid of a 2-dehydro-L-idonate. | [Purification Methods]
Crystallise 2-keto-L-gulonic acid from half its weight of water, wash it with Me2CO and dry it in vacuo. [Reichstein et al. Helv Chim Acta 17 311 1934, NMR: Crawford et al. J Am Chem Soc 102 2220 1980. Beilstein 3 IV 1985.] |
