angiotensin II. They are divided, according to their predominant
biological activity, into three major groups: glucocorticoids,
chiefly influencing carbohydrate, fat, and protein metabolism;
mineralocorticoids, affecting the regulation of electrolyte and
water balance; and C19 androgens. Some corticosteroids exhibit
both types of activity in varying degrees, and others exert only
one type of effect. The corticosteroids are used clinically for
