Roles Classification
Biological Role(s): prohormone
Any intra-glandular substance that acts as a precursor of a hormone, usually having minimal hormonal effect itself. Prohormones generally help in amplifying the effect of existing hormones.
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.
