Study Notes
Gastric Inhibitory Peptide (GIP)
- Produced by K cells in the mucosa of the duodenum and jejunum.
- Secretion is stimulated by glucose and fat in the duodenum.
- In large doses, it inhibits gastric secretion and motility.
- Stimulates insulin secretion, similar to gastrin, CCK, secretin, and glucagon.
- The only one of these that stimulates insulin secretion at blood levels comparable to those produced by oral glucose.
- Often called glucose-dependent insulinotropic peptide (GIP) due to its ability to stimulate insulin secretion in response to oral glucose.
