| dihydrotestosterone | <chemical> Chemical name: Androstan-3-one, 17-hydroxy-, (5alpha,17beta)- (12 Dec 1998) |
|---|---|
| dihydrouracil | 5,6-Dihydrouracil;a reduction product of uracil and one of the intermediates of uracil catabolism. (05 Mar 2000) |
| dihydrouracil dehydrogenase | <enzyme> Uses nad Registry number: EC 1.3.1.1 Synonym: dihydrothymine dehydrogenase (26 Jun 1999) |
| dihydrouracil oxidase | <enzyme> Oxygen dependent; no cofactor required, forms uracil irreversibly; enzyme from rhodosporidium toruloides Registry number: EC 1.3.3.- (26 Jun 1999) |
| dihydrouridine | <biochemistry> An unusual pyrimidine which is the result of adding two hydrogen atoms to a uridine (another nitrogenous base). It is found only in tRNA molecules. (09 Oct 1997) |
| dihydroxy- | <prefix> Prefix denoting addition of two hydroxyl groups; as a suffix, becomes -diol. (05 Mar 2000) |
| dihydroxyacetone | <chemical> 1,3-dihydroxy-2-propanone. A ketotriose compound. Its addition to blood preservation solutions results in better maintenance of 2,3-diphosphoglycerate levels during storage. It is readily phosphorylated to dihydroxyacetone phosphate by triokinase in erythrocytes. In combination with naphthoquinones it acts as a sunscreening agent. Chemical name: 2-Propanone, 1,3-dihydroxy- (12 Dec 1998) |
| dihydroxyacetone phosphate | This is an intermediate molecule involved in the fourth step of glycolysis. Dihydroxyacetonephosphate is created from fructose 1,6-bisphosphate. In step 5, it is converted into its positional isomer, glyceraldehyde3-phosphate, with the aid of triose-phosphate isomerase. (09 Oct 1997) |
| dihydroxyaluminum aminoacetate | Dihydroxy(glycinato)aluminum; (glycinato-N,O) dihydroxyaluminum;basic aluminum glycinate, a basic aluminum salt of aminoacetic acid containing small amounts of aluminum hydroxide and aminoacetic acid; used as an antacid in hyperchlorhydria and peptic ulcer. (05 Mar 2000) |
| dihydroxyaluminum sodium carbonate | Aluminum sodium carbonate hydroxide;a gastric antacid. (05 Mar 2000) |
| dihydroxycholecalciferols | Cholecalciferols substituted with two hydroxy groups in any position. (12 Dec 1998) |
| dihydroxydihydrobenzopyrenes | <chemical> Benzopyrenes saturated in any two adjacent positions and substituted with two hydroxyl groups in any position. The majority of these compounds have carcinogenic or mutagenic activity. Pharmacological action: carcinogens, mutagens. (12 Dec 1998) |
| dihydroxynaphthalene oxygenase | <enzyme> Also catalyses ring cleavage in an extradiol mode: between a hydroxylated and an adjacent non-hydroxylated carbon Registry number: EC 1.13.- Synonym: 1,2-dihydroxynaphthalene dioxygenase (26 Jun 1999) |
| dihydroxyphenylacetic acid reductase | <enzyme> Converts dihydroxyphenyl acetic acid to dihydroxyphenylethanol Registry number: EC 1.- Synonym: dopac reductase (26 Jun 1999) |
| dihydroxytryptamines | Tryptamine substituted with two hydroxyl groups in any position. Some are cytotoxic serotonin analogs that are preferentially taken up by serotonergic neurons and then destroy those neurons. (12 Dec 1998) |
