Hormones manufactured by the body from cholesterol and protein.
Group of hormones secreted by the testes, ovaries, adrenal cortex and placenta, such as androgens and estrogens.
Hormones ("chemical messengers," see above) that include molecules arranged in a particular chemical structure resembling a ring, which makes them "steroids." Steroids as a chemical family include some hormones, vitamins, drugs, and elements of the body.
Chemicals made by ovaries and adrenal glands that have a common structure, such as estrogen, testosterone, and cortisone.
Hormones made by reproductive organs and by the adrenal glands that have a certain chemical structure in common.
Hormones your body makes in your adrenal glands from cholesterol.
Steroid hormones are steroids which act as hormones. They can be grouped into five groups by the receptors to which they bind: glucocorticoids, mineralocorticoids, androgens, estrogens, and progestagens. Vitamin D derivatives are a sixth closely related hormone system with homologous receptors, though technically sterols rather than steroids.
A class of hormones synthesized by glands of the endocrine system that, by virtue of their nonpolar nature, are able to pass directly through the plasma membrane of a cell. Steroid hormones act by binding to and activating transcription factors called steroid hormone receptors.
