Re: What are peptide hormones?
 

Peptide hormones are signalling substances (hormones) that are peptides, i. e. that are assembled as a chain of amino acids.

Examples:

-Insulin
The peptide hormone insulin regulates the absorption of glucose in body cells. It has a glucose-lowering effect and plays an essential role in the treatment of diabetes mellitus. Insulin is the natural antagonist of the hormone
glucagon.

-Atrial natriuretic peptide (ANP)

-Human growth hormone (HGH)
