Question 8#

The secretin-glucagon family of gut hormones includes all of the following structurally related peptides EXCEPT:

A. Somatostatin (SST)
B. Glucose-dependent insulinotropic polypeptide ( GIP)
C. Glucagon-like peptide-1 (GLP-1)
D. Vasoactive intestinal polypeptide (VIP)

Correct Answer is A


Peptide hormones produced by enteroendocrine cells of the intestine are grouped into families based on their amino acid structural similarity. The secretin-glucagon family of hormones includes glucose-dependent insulinotropic polypeptide (GIP), glucagon-like peptide-1 (GLP-1), vasoactive intestinal polypeptide (VIP), peptide histidine isoleucine (PHI), growth hormone-releasing hormone (GHRH), and pituitary adenylyl cyclase-activating peptide (PACAP).
