| 2,3-diketo-l-gulonate | A product of catabolism of vitamin C; formed from l-dehydroascorbate; it has no vitamin C activity. (05 Mar 2000) |
| 2,3-diketogulonic acid | <chemical> Threo-2,3-hexodiulosonic acid. Metabolite of ascorbic acid and the oxidised form of the lactone dehydroascorbic acid. Chemical name: threo-2,3-Hexodiulosonic acid (12 Dec 1998) |
| 2,3-diphosphoglycerate | A highly anionic organic phosphate which is present in human red blood cells at about the same molar ratio as haemoglobin. It binds to deoxyhemoglobin but not the oxygenated form, therefore diminishing the oxygen affinity of haemoglobin. This is essential in enabling haemoglobin to unload oxygen in tissue capillaries. It is also an intermediate in the conversion of 3-phosphoglycerate to 2-phosphoglycerate by phosphoglycerate mutase (EC 5.4.2.1). (12 Dec 1998) |

| 2,4,5-trichlorophenoxyacetic acid | <chemical> (2,4,5-trichlorophenoxy)acetic acid. An herbicide with strong irritant properties. Use of this compound on rice fields, orchards, sugarcane, rangeland, and other noncrop sites was terminated by the epa in 1985. Pharmacological action: herbicides. Chemical name: Acetic acid, (2,4,5-trichlorophenoxy)- (12 Dec 1998) |
