| inositol 1,4,5-trisphosphate | <chemical> Intracellular messenger formed by the action of phospholipase c on phosphatidylinositol 4,5-bisphosphate, which is one of the phospholipids that make up the cell membrane. Inositol 1,4,5-trisphosphate is released into the cytoplasm where it releases calcium ions from internal stores within the cell's endoplasmic reticulum. These calcium ions stimulate the activity of b kinase or calmodulin. Chemical name: D-myo-Inositol, 1,4,5-tris(dihydrogen phosphate) (12 Dec 1998) |
| inositol-1,4,5-trisphosphate 5-phosphatase | <enzyme> does not act on inositol 1,4-bisphosphate or inositol 1,3,4-trisphosphate Registry number: EC 3.1.3.56 Synonym: inositol triphosphatase, myoinositol trisphosphatase, inositol polyphosphate 5-phosphatase, ip3-5-phosphatase, inositol-1,4,5-trisphosphate 5'-phosphatase, ins(1,4,5)p3 5'-phosphatase (26 Jun 1999) |
| inositol-1,4-bisphosphate 1-phosphatase | <enzyme> Acts only on inositol (1,4)-bisphosphate and inositol (1,3,4)-trisphosphate Registry number: EC 3.1.3.57 Synonym: ip2 1-phosphatase, d-myo-inositol (1,4)-bisphosphate 1-phosphatase, inositol bisphosphatase, inositol-1,4-bisphosphate-1-phosphatase, myoinositol diphosphatase, inositol polyphosphate 1-phosphatase (26 Jun 1999) |
| inositol-1,4-bisphosphate 4-phosphohydrolase | <enzyme> Soluble rat brain enzyme highly specific for inositol 1,4-bisphosphate; does not act on inositol 1-phosphate or inositol 1,4,5-trisphosphate Registry number: EC 3.1.3.- Synonym: ibp 4-phosphohydrolase (26 Jun 1999) |
| inositol 1-alpha-galactosyltransferase | <enzyme> Catalyses conversion of udpgalactose plus myo-inositol to galactinol plus udp Registry number: EC 2.4.1.123 Synonym: galactinol synthase (26 Jun 1999) |

| inositol lipid | A membrane-anchored phospholipid that transduces hormonal signals by stimulating the release of any of several chemical messengers. (09 Oct 1997) |
| inositol NAD epimerase | <enzyme> Converts myo-inositol to scyllo-inositol and neoinositol; inosose also formed and reverse reaction Registry number: EC 1.1.1.- (26 Jun 1999) |

| inositol phosphate | Virtually all of the possible phosphorylated states of inositol have been reported to occur in living tissues. The hexaphosphate, phytic acid, is abundant in many plant tissues and is a powerful calcium chelator. See: phosphatidyl inositol 3 kinase. (18 Nov 1997) |
| inositol phosphates | Phosphoric acid esters of inositol. They include mono- and polyphosphoric acid esters, with the exception of inositol hexaphosphate which is phytic acid. (12 Dec 1998) |
