Roles Classification
Chemical Role(s): Bronsted base
A molecular entity capable of accepting a hydron from a donor (Bronsted acid).
(via organic amino compound )
Biological Role(s): hormone
Originally referring to an endogenous compound that is formed in specialized organ or group of cells and carried to another organ or group of cells, in the same organism, upon which it has a specific regulatory function, the term is now commonly used to include non-endogenous, semi-synthetic and fully synthetic analogues of such compounds.
