| sugars | Those carbohydrates (saccharides) having the general composition (CH2O)n and simple derivatives thereof. Although the simple monomeric sugars (glycoses) are often written as polyhydroxy aldehydes or ketones, e.g., HOCH2-(CHOH)4-CHO for aldohexoses (e.g., glucose) or HOCH2-(CHOH)3-CO-CH2OH for 2-ketoses (e.g., fructose), cyclization can give rise to varied structures as described below. Sugars are generally identifiable by the ending -ose or, if in combination with a nonsugar (aglycon), -oside or -osyl. Sugars especially d-glucose, are the chief source of energy, by oxidation, in nature, and they and their derivatives (e.g., d-glucosamine, d-glucuronic acid), in polymeric form, are major constituents of mucoproteins, bacterial cell walls, and plant structural material (e.g., cellulose). Sugars are often found in combination with steroids (steroid glycosides) and other aglycons. (05 Mar 2000) |
| dTDP-sugars | Sugars or sugar derivatives bonded to dTDP. (05 Mar 2000) |

| inosine-uridine hydrolase | <enzyme> From crithidia fasciculata; hydrolyzes the n-glycosidic bonds of purine and pyrimidine nucleosides Registry number: EC 3.2.2.- Synonym: inosine-uridine preferring nucleoside hydrolase, iu-nucleoside hydrolase (26 Jun 1999) |
| uridine | <biochemistry> The ribonucleoside formed by the combination of ribose and uracil. (18 Nov 1997) |
| uridine 5'-(alpha-D-galactopyranosyl pyrophosphate) NAD 2-hexosyl oxidoreductase | <enzyme> Converts udpgalactose (pyranose form) to 2-keto-galactose which rearranges to furanose form Chemical name: UDPgalactose nad 2-hexosyl oxidoreductase Registry number: EC 1.1.1.- (26 Jun 1999) |
| uridine 5'-monophosphate | Uridine esterified by phosphoric acid on one or more sugar hydroxyl groups; UMP is typically uridine 5'-monophosphate; 2' and 3' derivatives also occur; precursor for the biosynthesis of other pyrimidine nucleotides. Synonym: UMP synthase, uridine 5'-monophosphate. Uridylic acid synthase, a bifunctional enzyme that contains the activities of both orotate phosphoribosyltransferase and orotidine-5'-monophosphate decarboxylase; catalyses a key step in pyrimidine biosynthesis; a deficiency of this enzyme leads to orotic aciduria. (05 Mar 2000) |
| uridine 5'-monophosphate synthase | <chemical> Consists of orotate phosphoribosyltransferase EC 2.4.2.10 and orotidylate decarboxylase EC 4.1.1.23 Chemical name: synthase, uridylate Synonym: ump synthase, uridine 5'-phosphate synthase, uridylate synthase (26 Jun 1999) |
| uridine 5'-triphosphate | <biochemistry> Uridine esterified with triphosphoric acid at its 5'-position; the immediate precursor of uridylic acid residues in RNA. (05 Mar 2000) |
| uridine diphosphogalactose | A pyrophosphate group links the 5'-position of uridine and the 1 position of d-galactose. (05 Mar 2000) |
| uridine diphosphoglucose | A pyrophosphate group links the 5'-position of uridine and the 1-position of d-glucose; an intermediate in glycogen biosynthesis. Synonym: UDPglucose. Acronym: UDPG (05 Mar 2000) |
| uridine diphosphoglucose 4-epimerase | <enzyme> A necessary enzyme in the metabolism of galactose. It reversibly catalyses the conversion of udpglucose to udpgalactose.
