prohormone

 [pro-hor´mōn]
a precursor of a hormone, such as a polypeptide that is cleaved to form a shorter polypeptide hormone or a steroid that is converted to an active hormone by peripheral metabolism. Called also prehormone.

(prō-hōr'mōn),
1. An intraglandular precursor of a hormone; for example, proinsulin. Compare: prehormone.
2. Obsolete term formerly used to designate a substance developed in serum that antagonizes a specific antihormone, and thus enhances the action of the corresponding hormone.
