It is mainly produced in endocrine cells located in the stomach, in the mucosal layer of the fundus, and it is secreted into bloodstream where it circulates in higher amounts than ghrelin (2:1).Although Des-G was previously thought of as a non-functional peptide, since it does not activate GHS-R1a, recent studies have shown t...
