Overview

myoglobin


Show Summary Details

Quick Reference

A globular protein occurring widely in muscle tissue as an oxygen carrier. It comprises a single polypeptide chain and a haem group, which reversibly binds a molecule of oxygen. This is only relinquished at relatively low external oxygen concentrations, e.g. during strenuous exercise when muscle oxygen demand outpaces supply from the blood. Myoglobin thus acts as an emergency oxygen store.
