Which is the main mineralocorticoid hormone?

Mineralocorticoids are responsible for regulating the concentration of minerals in the body fluids. The main mineralocorticoid is aldosterone. It increases reabsorption of sodium from the urine into the blood and it stimulates excretion of potassium into the urine. Aldosterone is released in response to a drop in the blood sodium concentration or blood pressure or to a rise in the blood potassium concentration.
