1. Phosphatidylinositol

   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 phosphatidylglycerides. In such molecules the isomer of the inositol group is assumed to be the myo- conformer unless otherwise stated. Typically phosphatidylinositols form a minor component on the cytosolic side of eukaryotic cell membranes. The phosphate group gives the molecules a negative charge at physiological pH. The form of phosphatidylinositol comprising the isomer muco-inositol acts as a sensory receptor in the taste function of the sensory system. In this context it is often referred to as PtdIns, but that does not imply any molecular difference from phosphatidylinositols comprising the myo- conformers of inositol. The phosphatidylinositol can be phosphorylated to form phosphatidylinositol phosphate (PI-4-P, referred to as PIP in close context or informally), phosphatidylinositol bisphosphate (PIP2) and phosphatidylinositol trisphosphate (PIP3). All lipids based on phosphatidylinositol are known as inositides, or sometimes phosphoinositides.

1. Phosphatidylinositol

   Phosphatidylinositol consists of a very large family of complex compounds as illustrated on the right. They are negatively charged due to the phosphate group and are a minor component in the cytosolic side of eukaryotic cell membranes. The specific lipid chains are typically not identified and the specific isomer of the nine possible isomers of inositol is not specified. The specific phosphatidylinositol using the isomer, muco-inositol is used as a sensory receptor in the gustatory modality of the sensory system. It is typically identified as PtdIns in the sensory literature. The other forms of phosphatidylinositol are commonly addressed as PI in the more general biochemical literature. The phosphatidylinositol can be phosphorylated to form phosphatidylinositol phosphate, phosphatidylinositol bisphosphate and phosphatidylinositol trisphosphate. PIP, PIP2 and PIP3 are collectively called phosphoinositides.
