1. (Physiological Chem.) A chemical substance formed in one
organ and carried in the circulation to another organ on
which it exerts a specific effect on cells at a distance
from the producing cells; thus, pituitary hormones
produced in the brain may have effects on cells in distant
parts of the body..
[Webster 1913 Suppl. +PJC]
2. (Physiological Chem.) a chemical substance, whether
natural or synthetic, that functions like a hormone in a
living organism. Thus, synthetic steroid hormones may be
more effective than their natural counterparts.
[PJC]
3. (Bot.) A substance that controls growth rate or
differentiation in plants; also called phytohormone. The
most well-known are the auxins that stimulate growth at
the growing tips of plants, and control root formation and
the dropping of leaves; and the gibberellins, which are
used in agriculture to promote plant growth.
