Mineralocorticoid Activity

Meaning

Mineralocorticoid Activity refers to the specific biological effects mediated by the class of adrenal steroid hormones, predominantly aldosterone, which are responsible for regulating the body’s balance of mineral ions and fluid volume. This activity is fundamentally important for maintaining stable plasma volume, regulating blood pressure, and ensuring the precise balance of sodium and potassium ions across cell membranes. Clinically, dysregulation of this activity is a primary cause of certain forms of hypertension and electrolyte imbalance.
