Steroid hormones can be classified into several categories based on their chemical structure and function. Some common classifications of steroid hormones include:
1. Glucocorticoids: These hormones are involved in regulating metabolism, immune response, and stress response. Examples include cortisol and cortisone.
2. Mineralocorticoids: These hormones regulate electrolyte balance and fluid balance in the body. Examples include aldosterone.
3. Androgens: These hormones are responsible for the development of male characteristics and reproductive function. Examples include testosterone and dihydrotestosterone.
4. Estrogens: These hormones are responsible for the development of female characteristics and reproductive function. Examples include estradiol and estrone.
5. Progestogens: These hormones are involved in regulating the menstrual cycle and pregnancy. Examples include progesterone.
6. Vitamin D: Although not traditionally considered a steroid hormone, vitamin D is derived from cholesterol and has hormone-like functions in the body, including regulating calcium and phosphorus metabolism.
These classifications are based on the specific functions and structures of the hormones, but it is important to note that there is some overlap between the categories and some hormones may have multiple functions.
