WebInositol 1,4,5-trisphosphate (InsP3) mobilizes calcium from nonmitochondrial pools, transiently elevating intracellular calcium concentrations. In Xenopus oocytes, calcium-dependent chloride channels open in the plasma membrane, and they are seen under the described voltage-clamp conditions as depolarizing currents ( 14, 15 ). PI has a polar and non-polar region, making the lipid an amphiphile. Phosphatidylinositol is classified as a glycerophospholipid that contains a glycerol backbone, two non-polar fatty acid tails, a phosphate group substituted with an inositol polar head group. The most common fatty acids of … See more Phosphatidylinositol (or Inositol Phospholipid) consists of a family of lipids as illustrated on the right, where red is x, blue is y, and black is z, in the context of independent variation, a class of the The form of … See more • PI 3-kinase • Inositol phosphate • Phosphatidylinositol 3-phosphate • Phosphatidylinositol 4-phosphate See more • Phosphatidylinositols at the U.S. National Library of Medicine Medical Subject Headings (MeSH) • Phosphatidylinositol at Lipid Library See more The synthesis of phosphatidylinositol in the laboratory is catalyzed by phosphatidylinositol synthase and involves CDP-diacylglycerol and L-myo-inositol.
