Corticosteroids are a class of steroid hormones that are produced in the adrenal cortex of vertebrates, as well as the synthetic analogues of these hormones. Two main classes of corticosteroids, glucocorticoids and mineralocorticoids, are involved in a wide range of physiologic processes, including stress response, immune response, and regulation of inflammation, carbohydrate metabolism, protein catabolism, blood electrolyte levels, and behavior.

Some common naturally occurring steroid hormones are cortisol (C

5), corticosterone (C

30O
4), cortisone (C
21H
28O
5) and aldosterone (C
21H
28O
5). (Note that aldosterone and cortisone share the same chemical formula but the structures are different.) The main corticosteroids produced by the adrenal cortex are cortisol and aldosterone.
