An adrenocortical steroid hormone that increases gluconeogenesis, exerts an antiinflammatory effect, and influences many body functions. The three glucocorticoids are cortisol (hydrocortisone), corticosterone, and cortisone. Glucocorticoids promote the release of amino acids from muscle, mobilize fatty acids from fat stores, and increase the ability of skeletal muscles to maintain contractions and avoid fatigue.
