| inosine triphosphate | <chemical> Inosine 5'-(tetrahydrogen triphosphate). An inosine nucleotide containing three phosphate groups esterified to the sugar moiety. Synonym: irppp. Chemical name: Inosine 5'-(tetrahydrogen triphosphate) (12 Dec 1998) |
| inositol triphosphate phosphomonoesterase | <enzyme> Human erythrocyte membrane enzyme converts inositol 1,4,5-trisphosphate into inositol 1,4-bisphosphate Registry number: EC 3.1.3.- Synonym: intp esterase, triphosphoinositide phosphomonoesterase, inositol triphosphate phosphatase, inositol triphosphate 5-phosphatase (26 Jun 1999) |
| 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) |
| erythro-dihydrobiopterin triphosphate synthetase | <enzyme> Converts 2-amino-6(5'-triphosphoribosyl)-amino-5-or -6-formamido-6-hydroxypyrimidine into quinonoid-d-erythrodihydroneopterin triphosphate Registry number: EC 3.5.4.- Synonym: dhbp-tp-synthetase (26 Jun 1999) |
| ethenoadenosine triphosphate | 1,n-6-ethenoadenosine triphosphate. A fluorescent analog of adenosine triphosphate. (12 Dec 1998) |
| 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 triphosphate | A molecule which consists of the nitrogenous base uracil linked to the sugar ribose and which has a chain of three phosphate groups attached to the ribose in a linear fashion. UTP is required during transcription since it is a direct precursor of RNA. (09 Oct 1997) |
