hormone


hormone
A substance secreted by specialized cells that affects the metabolism or behaviour of other cells possessing functional receptors for the hormone. Hormones may be hydrophilic, like insulin, in which case the receptors are on the cell surface, or lipophilic, like the steroids, where the receptor can be intracellular. See Tables H2 and H3.
