Steroid Hormones

Testosterone is the primary male sex hormone responsible for the development of male reproductive tissues. Estrogen and progesterone are female sex hormones, while insulin is a hormone that regulates blood sugar levels.

Progesterone is a hormone produced mainly in the ovaries and plays a crucial role in preparing the uterus for pregnancy, while testosterone is a male sex hormone, insulin regulates blood sugar levels, and estrogen is another female sex hormone but with different functions than progesterone.

Pregnenolone is a key molecule used in the production of steroid hormones such as cortisol, testosterone, and estradiol. While the other three molecules listed are important steroid hormones, pregnenolone is the precursor molecule from which they are derived.

Estradiol is a steroid hormone and the primary female sex hormone. Testosterone, insulin, and serotonin are different molecules with unique functions in the body.

Cortisol is a hormone that plays a crucial role in the body's response to stress. It helps regulate metabolism, immune response, and blood pressure, among other functions. Serotonin, insulin, and melatonin are not directly involved in stress regulation like cortisol.

Aldosterone is a hormone produced by the adrenal glands that helps regulate the balance of sodium and potassium in the body. Insulin is not specifically involved in sodium and potassium balance. Adrenaline is the hormone responsible for the fight or flight response. Estrogen is a female sex hormone and is not directly related to the regulation of sodium and potassium.

Steroid hormones are synthesized from cholesterol in the body through various biochemical pathways.
