Encyclopedia Article for corticosteroid


any of a group of more than 40 organic compounds belonging to the steroid family and present in the cortex of the adrenal glands. Of these substances, about six are hormones, secreted into the bloodstream and carried to other tissues, where they elicit physiological responses. (The other corticoids, inactive as hormones, appear to be intermediates in the biosynthesis of the hormones from cholesterol.) The hormones are categorized, according to their principal effects on the target organs, as either glucocorticoids or mineralocorticoids.
