Inositol is also named as 1,2,3,5-trans-4,6-Cyclohexanehexol, cis-; AI3-16111; CCRIS 6745; Dambose; Inosital; Inositene; Inositina; Inositol (VAN). It is white powder. Inositol or cyclohexane-1,2,3,4,5,6-hexol is a chemical compound with formula C6H12O6 or (-CHOH-)6, a sixfold alcohol (polyol) of cyclohexane. It is almost tasteless, with a small amount of sweetness. It is soluble in water, slightly soluble in ethanol, acetic acid, ethylene glycol and glycerin, insoluble in ether, acetone and chloroform.
Inositol or its phosphates and associated lipids are found in many foods, in particular fruit, especially cantaloupe and oranges. In plants, the hexaphosphate of inositol, phytic acid or its salts, the phytates, are found. These serve as phosphate stores in the seed. Phytic acid occurs also in cereals with high bran content and also nuts and beans, but inositol when present as phytate is not directly bioavailable to humans in the diet, since it is not digestible (s)ome food preparation techniques partly break down phytates to change this. Inositol as it occurs in certain plant-derived substances such as lecithins, however, is well-absorbed and relatively bioavailable.

1. Uses of Inositol
Inositol has been used as an adulterant (or cutting agent) in many illegal drugs, such as cocaine, methamphetamine, and sometimes heroin. It is presumed that this use is connected with one or more of the substance’s properties of solubility, powdery texture, or reduced sweetness (50%) as compared with more common sugars. Inositol is also used as a stand-in for cocaine on television.
2. Function
Inositol and some of its mono and polyphosphates function as the basis for a number of signaling and secondary messenger molecules. They are involved in a number of biological processes, including:
*Insulin signal transduction

*Cytoskeleton assembly

*Nerve guidance (Epsin)

*Intracellular calcium (Ca2+) concentration control

*Cell membrane potential maintenance

*Breakdown of fats and reducing blood cholesterol

*Gene expression

4. Preparation of Inositol
Inositol is produced from glucose-6-phosphate (G-6-P) in two steps. First, G-6-P is isomerised by ISYNA1 to inositol 1-phosphate; then it is dephosphorylated by IMPase 1 to give free Inositol . In humans most inositol is synthesized in the kidneys, in typical amounts of a few grams per day.
