| thiamin mononitrate | Same action as thiamin hydrochloride. (05 Mar 2000) |
|---|---|
| thiamine | <chemical> 3-((4-amino-2-methyl-5-pyrimidinyl)methyl)-5-(2- hydroxyethyl)-4-methylthiazolium chloride. Chemical name: Thiazolium, 3-((4-amino-2-methyl-5-pyrimidinyl)methyl)-5-(2-hydroxyethyl)-4-methyl- chloride (12 Dec 1998) |
| thiamine deficiency | A nutritional condition produced by a deficiency of thiamine in the diet, characterised by anorexia, irritability, and weight loss. Later, patients experience weakness, peripheral neuropathy, headache, and tachycardia. In addition to being caused by a poor diet, thiamine deficiency in the united states most commonly occurs as a result of alcoholism, since ethanol interferes with thiamine absorption. In countries relying on polished rice as a dietary staple, beriberi prevalence is very high. (12 Dec 1998) |
| thiamine monophosphate | <chemical> Thiamine dihydrogen phosphate ester. The monophosphate ester of thiamine. Synonym: monophosphothiamine; vitamin b1 monophosphate. Chemical name: Thiazolium, 3-((4-amino-2-methyl-5-pyrimidinyl)methyl)-4-methyl-5-(2-(phosphonooxy)ethyl)-, chloride (12 Dec 1998) |
| thiamine pyrophosphatase | <enzyme> The coenzyme form of vitamin B1 (thiamine), deficiency of which causes beri beri. Forms the prosthetic group of pyruvate dehydrogenase, _ ketoglutarate dehydrogenase and transketolase, in which it is involved in transfer of a 2 carbon unit. Marker for the trans cisternae of the Golgi complex. (18 Nov 1997) |
| thiamine pyrophosphate | <biochemistry> Co carboxylase. A cofactor that has an unusually acidic carbon atom able to form carbon carbon bonds. Found in pyruvate dehydrogenase and transketolase. (18 Nov 1997) |
| thiamine triphosphate | <chemical> 3-((4-amino-2-methyl-5-pyrimidinyl)methyl)-4-methyl-5-(4,6,8,8-tetrahydroxy-3,5,7-trioxa-4,6,8-triphosphaoct-1-yl)thiazolium hydroxide, inner salt, p,p',p''-trioxide. The triphosphate ester of thiamine. In leigh's disease, this compound is present in decreased amounts in the brain due to a metabolic block in its formation. Chemical name: Thiazolium, 3-((4-amino-2-methyl-5-pyrimidinyl)methyl)-4-methyl-5-(4,6,8,8-tetrahydroxy-3,5,7-trioxa-4,6,8-triphosphaoct-1-yl)-, inner salt, P,P',P''-trioxide (12 Dec 1998) |
