  • Steroid Hormones
    Bio signaling molecules derived from cholesterol, classified into five groups based on their physiological effects.
  • Cholesterol
    Precursor molecule used to build all classes of steroid hormones, forming their structural backbone.
  • Androgens
    Group of steroid hormones produced by gonads, responsible for male sexual development.
  • Estrogens
    Steroid hormones produced by gonads, essential for female sexual development.
  • Progestins
    Steroid hormones from gonads, crucial for regulating menstrual cycle and pregnancy in females.
  • Glucocorticoids
    Steroid hormones from adrenal cortex, involved in metabolism of carbohydrates, proteins, and lipids.
  • Mineralocorticoids
    Steroid hormones from adrenal cortex, regulate kidney excretion of salt and water.
  • Testosterone
    Classic androgen, key molecule for male sexual development and secondary sex characteristics.
  • Estradiol
    Primary estrogen, central to female sexual development and reproductive function.
  • Progesterone
    Main progestin, vital for menstrual cycle regulation and maintenance of pregnancy.
  • Cortisol
    Principal glucocorticoid, modulates metabolism and stress responses in the body.
  • Aldosterone
    Major mineralocorticoid, controls salt and water balance by acting on the kidneys.
  • Gonads
    Organs producing gametes, such as testes and ovaries, source of androgens, estrogens, and progestins.
  • Adrenal Cortex
    Outer region of adrenal glands, site of glucocorticoid and mineralocorticoid synthesis.
  • Bio Signaling Molecules
    Compounds released by cells or glands, affecting distant cells to coordinate physiological responses.
