5), corticosterone (C 21 H 30 O 4), cortisone (C 21 H 28 O 5) and aldosterone (C 21 H 28 O 5) (cortisone and aldosterone are isomers). The main corticosteroids produced by the adrenal cortex are cortisol and aldosterone. [1] The etymology of the cortico-part of the name refers to the adrenal cortex, which makes these steroid hormones. Thus a ...
Aldosterone is the primary of several endogenous members of the class of mineralocorticoids in humans. [citation needed] Deoxycorticosterone is another important member of this class. Aldosterone tends to promote Na + and water retention, and lower plasma K + concentration by the following mechanisms:
It selectively stimulates secretion of aldosterone. The secretion of aldosterone has a diurnal rhythm. Control of aldosterone release from the adrenal cortex: [citation needed] The role of the renin–angiotensin system: Angiotensin is involved in regulating aldosterone and is the core regulator. Angiotensin II acts synergistically with potassium.

Adrenal steroids such as glucocorticoids and mineralocorticoids are commonly used as treatments in diseases such as Congenital adrenal hyperplasia. [2] CAH commonly causes overproduction of androgens, glucocorticoid treatment is used to reduce Adrenocorticotropic hormone (ACTH) and reduce the production of androgens allowing for symptoms of CAH to be managed though treatment is required to be ...
The name mineralocorticoid derives from early observations that these hormones were involved in the retention of sodium, a mineral.The primary endogenous mineralocorticoid is aldosterone, although a number of other endogenous hormones (including progesterone [1] and deoxycorticosterone) have mineralocorticoid function.
Corticosterone is converted to aldosterone by aldosterone synthase, found only in the mitochondria of glomerulosa cells. Glomerulosa cells are found in the zona glomerulosa , which is the most superficial region of endocrine cells in the adrenal cortex .
In humans and other animals, the adrenocortical hormones are hormones produced by the adrenal cortex, the outer region of the adrenal gland.These polycyclic steroid hormones have a variety of roles that are crucial for the body's response to stress (for example, the fight-or-flight response), and they also regulate other functions in the body.
