inositol

 [ĭ-no´sĭ-tol]
a cyclic sugar alcohol; usually referring to the most abundant isomer, myo-inositol, which is found in many plant and animal tissues and is often classified as part of the vitamin B complex.

in·o·si·tol

(in-ō'si-tōl, -tol),
A member of the vitamin B complex necessary for growth of yeast and of mice; absence from the diet causes alopecia and dermatitis in mice and "spectacle eyes" in rats. It occurs in a number of stereoisomeric forms: cis-, epi-, allo-, neo-, myo-, muco-, chiro-, and scyllo-inositols; the most abundant naturally occurring inositol is myo-inositol (usually meant when "inositol" occurs without a prefix).

inositol

/ino·si·tol/ (in-o´sĭ-tol) a cyclic sugar alcohol, the fully hydroxylated derivative of cyclohexane; usually referring to the most abundant isomer, myo -inositol, which occurs in many plant and animal tissues and microorganisms and is often classified as a member of the vitamin B complex.
inositol 1,4,5-triphosphate (InsP3, IP3)  a second messenger that causes the release of calcium from certain intracellular organelles.

inositol

(ĭ-nō′sĭ-tôl′, -tōl′, ī-nō′-)
n.
Any of nine isomeric alcohols, C6H12O6·2H2O, that are precursors to various signaling molecules.

inositol

[inō′sətōl, inos′-]
an isomer of glucose that occurs widely in plant and animal cells. Although inositol has no current therapeutic use, it is an essential cell constituent.

inositol

Biochemistry A structure in phospholipids–eg, phosphoinositol; its main isomeric form is myo-inositol; it is present in breast milk, and may ↓ complications of prematurity and ↓ death due to lung disease, bronchopulmonary dysplasia, retinopathy of prematurity

in·o·si·tol

(in-ō'si-tol)
A member of the vitamin B complex.

inositol (ī·nōˑ·s·tl),

n See vitamin B8.

in·o·si·tol

(in-ō'si-tol)
A member of the vitamin B complex necessary for growth of yeast.

inositol (inō´sitol),

n an essential growth factor in tissue culture with no known requirement. It has been used therapeutically in the management of diseases associated with the metabolism of fat.

inositol

a cyclic sugar alcohol, C6H12O6; usually referring to the most abundant isomer, myo-inositol, which is found in many plant and animal tissues.

inositol 1,4,5-trisphosphate
intracellular second messenger released from phosphatidyl 4,5-bisphosphate in response to agonist-dependent, GTP-G protein-activated phospholipase C. Called also IP3. Causes release of Ca2+ from intracellular stores, thereby activating calmodulin.
