inositol

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-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.
