| 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) |
