All are true of G.I.P. except
|A||Secreted by K cells of Duod. & jejunum|
|B||(+)ed by glucose, fat in the duodenum|
|C||In large doses, it (-)s gastric secretion and mobility|
|D||It stimulates insulin secretion|
|E||Belongs to gastrin family of G.I. hormones.|
GIP is secreted by K cells of jejunum and duodenum.
Previously, it was called gastric – inhibitory peptide. Now, it is called glucose – dependent insulinotropic polypeptide (the two names indicate its two actions)
