| uridine diphosphate glucose | <chemical> A key intermediate in carbohydrate metabolism. Serves as a precursor of glycogen, can be metabolised into udpgalactose and udpglucuronic acid which can then be incorporated into polysaccharides as galactose and glucuronic acid. Also serves as a precursor of sucrose lipopolysaccharides, and glycosphingolipids. Chemical name: Uridine 5'-(trihydrogen diphosphate), P'-alpha-D-glucopyranosyl ester (12 Dec 1998) |
| uridine diphosphate glucose dehydrogenase | <enzyme> An enzyme that catalyses the oxidation of udpglucose to udpglucuronate in the presence of NAD+. Chemical name: UDPglucose:NAD+ 6-oxidoreductase Registry number: EC 1.1.1.22 (12 Dec 1998) |
| utp-glucose-1-phosphate uridylyltransferase | <enzyme> An enzyme that catalyses the formation of udpglucose from utp plus glucose 1-phosphate. Chemical name: UTP:alpha-D-glucose-1-phosphate uridylyltransferase Registry number: EC 2.7.7.9 (12 Dec 1998) |
| 4-coumaroyl-D-glucose hydroxylase | <enzyme> From sweet potato roots (ipomoea batatas); catalyses the conversion of p-coumaroyl-d-glucose to caffeoyl-d-glucose for chlorogenic acid biosynthesis in the presence of ascorbic acid; mw 33 kD; has weak polyphenol oxidase activity; also hydroxylates p-coumaric acid Registry number: EC 1.14.17.- Synonym: p-coumaroyl-d-glucose hydroxylase, cdg hydroxylase (26 Jun 1999) |
| liquid glucose | A pharmaceutic aid consisting of dextrose, dextrins, maltose, and water, obtained by the incomplete hydrolysis of starch. (05 Mar 2000) |
