GIP is a member of a family of structurally related hormones that includes secretin, glucagon, and vasoactive intestinal peptide. GIP (human) differs from GIP (porcine) at residues 18 and 34.  GIP is secreted from specific endocrine cells (K-cells) in the epithelium of the upper part of small intestine after ingestion of  food. Once released, GIP is subjected to NH2-terminal degradation by dipeptidyl peptidase-IV (DPP-IV), yielding GIP (3-42) as the primary metabolite which acts as a GIP receptor antagonist.
