| choline-phosphate cytidylyltransferase | <enzyme> An enzyme that catalyses the transfer of cytidylate (CMP) to choline phosphate to form CDPcholine. It is the rate-limiting enzyme in the choline pathway for the biosynthesis of phosphatidylcholine. Its activity is increased by glucocorticoids. Registry number: EC 2.7.7.15 (12 Dec 1998) |

| chromic phosphate P 32 colloidal suspension | A pure beta-emitting colloidal, nonabsorbable radiopharmaceutical administered into body cavities such as the pleural or peritoneal spaces to control malignant effusions. See: sodium phosphate P 32. (05 Mar 2000) |
| phosphate | <chemistry> A salt of phosphoric acid. Source: Websters Dictionary (01 Mar 1998) |
| phosphate acetyltransferase | <enzyme> An enzyme that catalyses the synthesis of acetylphosphate from acetyl-CoA and inorganic phosphate. Acetylphosphate serves as a high-energy phosphate compound. Chemical name: Acetyl-CoA:orthophosphate acetyltransferase Registry number: EC 2.3.1.8 (12 Dec 1998) |
| phosphate diabetes | Excessive secretion of phosphate in the urine due to a defect in tubular reabsorption; usually part of a more generalised abnormality, such as Fanconi syndrome. (05 Mar 2000) |
| phosphate group | <chemistry> A phosphate group on a larger molecule, where the phosphorus is single bonded to each of the four oxygens, and the other bond of one of the oxygens is attached to the rest of the molecule. This means that the entire group has a net negative charge of -3 (from the free second bonds on the oxygen atoms which are only bonded to the phosphorus atom). Often hydrogen atoms will be attached to the oxygens and sometimes double bonds between the phosphorus and an oxygen are present. (31 Dec 1997) |
| phosphate permease | <chemical> Isolated from van+ gene of neurospora crassa; transports vanadate Chemical name: permease, phosphate Synonym: permease, phosphate, pho4 gene product, pho5 gene product (26 Jun 1999) |
| phosphate tetany | Tetany due to the ingestion of an excess of alkaline phosphates (Na2HPO4 or K2HPO4); most commonly produced experimentally in animals by the injection of alkaline phosphate, which reduces the ionised calcium of the blood. (05 Mar 2000) |
| phosphatidylinositol 4-phosphate | <biochemistry> The intermediate in the biosynthesis of phosphatidylinositol 4,5-bisphosphate from phosphatidylinositol. (20 Sep 2002) |
| phosphatidylinositol 4-phosphate phosphatase | <enzyme> From human erythrocyte membranes Registry number: EC 3.1.3.- Synonym: ptdins-4p-phosphatase, phosphatidylinositol-4-phosphate monoesterase, ptdins4p monoesterase (26 Jun 1999) |
| phosphoribosylanthranilate isomerase-indoleglycerol-phosphate synthase | <chemical> EC 5.3.1.24 plus EC 4.1.1.48 Synonym: pai-igps, indoleglycerol phosphate synthase-phosphoribosyl anthranilate isomerase, prai-igps (26 Jun 1999) |
| clomacran phosphate | 2-Chloro-9-[3-(dimethylamino)propyl]acridan phosphate;a tranquilliser. (05 Mar 2000) |
| cobalamin (5'-phosphate)synthase | <enzyme> From pseudomonas denitrificans; catalyses the synthesis of cobalamin 5'-phosphate from GDP-cobinamide and alpha-ribazole 5'-phosphate, but also the synthesis of cobalamin from GDP-cobinamide and alpha-ribazole Registry number: EC 2.6.99.- Synonym: cobv gene product (26 Jun 1999) |
| cobinamide phosphate guanylyltransferase | <enzyme> From pseudomonas dentrificans; converts combinamide phosphate to GDP-cobinamide; occurs in a bifunctional protein with cobinamide kinase Registry number: EC 2.7.7.- Synonym: cbpg transferase (26 Jun 1999) |
| codeine phosphate | A water-soluble salt of codeine often used in the pharmaceutical preparation of codeine-containing liquid medications. (05 Mar 2000) |
