Corticosteroids can be broadly classified into two categories: glucocorticoids and mineralocorticoids. Glucocorticoids, such as cortisol, are involved in the regulation of carbohydrate metabolism and immune response. Mineralocorticoids, such as aldosterone, play a key role in maintaining electrolyte balance and blood pressure. Both types of corticosteroids are synthesized from cholesterol through a series of enzymatic reactions.
