| tartrate | <chemistry> A salt of tartaric acid. Origin: Cf. F. Tartrate. Source: Websters Dictionary (01 Mar 1998) |
| tartrate-resistant acid phosphatase | <biochemistry, enzyme> Acid phosphatase is present in bone, prostate, platelets, erythrocytes and spleen. Osteoclasts contain an isoenzyme that is resistant to tartrate, whereas, the isoenzyme in the prostate is sensitive. Tartrate-resistant acid phosphatase is elevated in the serum of patients with primary hypoparathyroidism, Paget disease, vertebral osteoporosis, T-cell lymphoma and in women after oophorectomy. Oestrogen replacement in osteoporotic postmenopausal women is associated with a decrease in tartrate-resistant acid phosphatase of 70% over 3 to 6 months. Acronym: TRAP (16 Dec 1997) |
| trimeprazine tartrate | 10-[3-(Dimethylamino)-2-methylpropyl]phenothiazine tartrate;a phenothiazine compound related chemically and pharmacologically to promazine but with a more pronounced histamine-antagonizing action; used for the symptomatic relief of pruritus. (05 Mar 2000) |
| levallorphan tartrate | 1-N-Allyl-3-hydroxymorphinan tartrate;the N-allyl analog of levorphanol, antagonistic to the actions of narcotic analgesics; used in the treatment of respiratory depression due to overdosage of narcotics. (05 Mar 2000) |
| levorphanol tartrate | L-3-Hydroxy-N-methylmorphinan tartrate dihydrate;an analgesic similar in action to morphine. (05 Mar 2000) |
| L-tartrate decarboxylase | <enzyme> Nad+ dependent enzyme; catalyses the decarboxylation of l-tartrate in pseudomonas sp. Group ve-2 forming glyceric acid and co2 via enzyme-bound oxaloglycolate Registry number: EC 4.1.1.- (26 Jun 1999) |
| L-tartrate dehydratase | <enzyme> From E coli; forms oxaloacetate and water; exists in an inactive low-molecular form, which is converted into the active enzyme in the presence of fe(2+) and thiol; related to class I fumarases Registry number: EC 4.2.1.32 Synonym: (r,r)-tartrate hydro-lyase (26 Jun 1999) |
