Information About

Inositol








Inositol, or '''cis-1,2,3,5-trans-4,6-cyclohexanehexol''', is a cyclic polyalcohol that plays an important role as a Second Messenger in a Cell , in the form of Inositol Phosphate s. It is found in many foods, namely Cereal s with high Bran content.

It is classified as a member of the Vitamin B complex, though it is not considered a Vitamin per se, since the human body can synthesize it.


STRUCTURE

The chemical formula of inositol is 6126. There are 9 Isomer s, all of which are called inositol.

The inositol ring is in the Chair Conformation . The 1st, 3rd, 4th, 5th and 6th Hydroxyl s are positioned Equatorial ly to the plane of the ring, while the 2nd hydroxyl group is positioned Axial ly to the plane of the ring.


SYNTHESIS

Inositol is synthesized from G6P in two steps. First G6P is Isomer ized by INYNA1 to ''myo''-inositol 1-phosphate, which is then dephosphorylated by IMPA1 to yield inositol.


FUNCTION

It is involved in :

It is also involved in the breakdown of Fat s and reducing blood Cholesterol .

Inositol phosphates are involved in Gene Expression (Wu 2003 and OShea 2003 both in Science).


CLINICAL IMPLICATIONS

Some preliminary results of studies on inositol supplements show promising results for people suffering from problems such as Bulimia , Panic Disorder and Bipolar Depression .

Inositol has been found in double-blind studies to be an effective treatment for Obsessive-compulsive Disorder (OCD) . It is equal in effectiveness to SSRIs and is virtually free from side effects {Link without Title} .
