inositol(redirected from mouse antialopecia factor)
Also found in: Dictionary, Thesaurus, Encyclopedia.
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.
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′-)
Any of nine isomeric alcohols, C6H12O6·2H2O, that are precursors to various signaling molecules.
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.
inositolBiochemistry 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
A member of the vitamin B complex.
n See vitamin B8.
A member of the vitamin B complex necessary for growth of yeast.
a cyclic sugar alcohol, C6H12O6; usually referring to the most abundant isomer, myo-inositol, which is found in many plant and animal tissues.
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.
