| Description: Hormones that don’t circulate are local hormones (paracrines). Those that act on the same cell that secretes them are autocrines. Hormones are either lipid-soluble (steroid hormones, thyroid hormones, nitric oxide) or water-soluble (amine hormones, peptide and protein hormones, eicosanoid hormones). Water-soluble hormones circulate freely in the plasma. Lipid-soluble hormones circulate bound to transport proteins.
