Mineralocorticoids are a class of corticosteroids, which are a class of steroid hormones. Mineralocorticoids are corticosteroids that influence salt and water balances (electrolyte balance and fluid balance). The primary mineralocorticoid is aldosterone, notable for a second keto group at the 18 position.
