Aldosterone molecule. Computer graphic of a molecule of the hormone aldosterone (chemical formula: C21.H28.O5). The atoms are shown as spheres, and are colour coded: carbon is purple, hydrogen is yellow, and oxygen is red. Aldosterone is a hormone released by the adrenal glands which helps maintain the body's water balance. It does this by increasing or decreasing uptake of sodium and potassium into tissues. Excess aldosterone levels in the blood can lead to high blood pressure and muscle weakness.
