Aldosterone
Aldosterone — A steroid hormone produced by the adrenal cortex that regulates sodium and potassium balance, studied alongside peptide hormones in endocrine research.
What Is Aldosterone?
Aldosterone is a steroid hormone (not a peptide) produced by the adrenal cortex that regulates sodium/potassium balance and blood pressure. It appears in the peptide glossary because aldosterone secretion is stimulated by angiotensin II, a key peptide hormone in the renin-angiotensin-aldosterone system (RAAS). Understanding aldosterone is essential for interpreting peptide-mediated blood pressure regulation.
RAAS Peptide Connection
- Angiotensinogen → Angiotensin I → Angiotensin II: Sequential proteolytic processing produces the active peptide
- AT1 receptor: Angiotensin II binding stimulates aldosterone secretion from adrenal glomerulosa
- ACE inhibitors: Block angiotensin I to II conversion, reducing aldosterone and blood pressure
