Autakoid

Also known as autacoid

Autacoids or autocoids are biological factors (molecules) which act like local hormones, have a brief duration, and act near their site of biosynthesis. The word autacoid comes from the Greek words "autos" (self) and "acos" (relief; i.e., drug). The effects of autacoids are primarily local, though large quantities can be produced and moved into circulation. Autacoids may thus have systemic effects by being transported via the circulation. These regulating molecules are also metabolized locally. In sum, these compounds typically are produced locally, act locally and are metabolized locally. Aut
