A mineralocorticoid steroid hormone secreted by the zona glomerulosa of the adrenal cortex, playing an essential role in regulating fluid-electrolyte balance and blood pressure. It acts upon the distal tubules of the kidneys, stimulating sodium and water reabsorption while promoting potassium and hydrogen excretion.
