myo-Inositol is naturally present in a variety of foods, although tables of food composition do not always distinguish between lecithin, the relatively bioavailable lipid form and the biounavailable phytate/phosphate form. [17] Foods containing the highest concentrations of myo-inositol and its compounds include fruits, beans, grains, and nuts ...
Phosphatidylinositol (PI), also known as inositol phospholipid, is a lipid composed of a phosphate group, two fatty acid chains, and one inositol molecule. It belongs to the class of phosphatidylglycerides and is typically found as a minor component on the cytosolic side of eukaryotic cell membranes.

myo-Inositol trispyrophosphate (ITPP) is an inositol phosphate, a pyrophosphate, a drug candidate, and a putative performance-enhancing substance, which exerts its biological effects by increasing tissue oxygenation.
Phytate. A phytase (myo-inositol hexakisphosphate phosphohydrolase) is any type of phosphatase enzyme that catalyzes the hydrolysis of phytic acid (myo-inositol hexakisphosphate) – an indigestible, organic form of phosphorus that is found in many plant tissues, especially in grains and oil seeds – and releases a usable form of inorganic phosphorus.

Inositol monophosphatase 2 is a 32 kDa enzyme that in humans is encoded by the IMPA2 gene. [4] [5] IMPA2 dephosphorylates myo-inositol monophosphate to myo-inositol.The function of IMPA2 appears to be similar to IMPA1 within tissues; however, the genes are expressed differently in various tissues with IMPA2 expressed at the highest level in certain tissues of the brain and the lumen of the kidney.

In enzymology, an inositol 2-dehydrogenase (EC 1.1.1.18) is an enzyme that catalyzes the chemical reaction. myo-inositol + NAD + 2,4,6/3,5-pentahydroxycyclohexanone + NADH + H + Thus, the two substrates of this enzyme are myo-inositol and NAD +, whereas its 3 products are 2,4,6/3,5-pentahydroxycyclohexanone, NADH, and H +.
