Question: is inhibin a peptide hormone?
Answer: Inhibin, a dimeric 32 kDa peptide hormone, is produced by ovarian granulosa and theca cells. Inhibin is a product of the gonads and is present in at least two biologically active forms (inhibin A and inhibin B) as well as in a variety of alpha subunit precursor forms.
