Sense: noun/1
Glucocorticoids are a specific subgroup of corticosteroids — the group of hormones produced by the adrenal cortex. Corticosteroids also include mineralocorticoids (which control salt and water balance), so not every corticosteroid is a glucocorticoid. Cortisol is the single most important natural glucocorticoid in humans, but glucocorticoids as a class include many synthetic drugs like prednisone and dexamethasone. Steroid hormones is the broadest category, covering not only adrenal hormones but also sex hormones such as estrogen and testosterone. For example, a patient with asthma may be prescribed a glucocorticoid inhaler (not a mineralocorticoid or a sex hormone), while the body naturally raises cortisol levels during stress.
Common collocations
Etymology
The word combines 'gluco-' (from Greek glykys, meaning sweet, referring to glucose) + 'cortic-' (from Latin cortex, meaning bark or outer layer, referring to the adrenal cortex) + '-oid' (from Greek -oeides, meaning resembling). It was coined in the 1940s after researchers discovered that hormones from the adrenal cortex affect the body's use of glucose. The plural form glucocorticoids refers to the entire class of these substances.
