The contribution of the pancreas and the intestine to the regulation of lipolysis in birds. I. Existence of highly potent lipolytic factors in ileum extracts.
Duck intestinal extracts were separated into three main peaks of proteins by chromatography on P6 BioGel columns. The first, which crossreacted with glucagon antibodies, gut "GLI", did not stimulate lipolysis in isolated chicken adipocytes. Both second and third peaks, corresponding to smaller molecular-size peptides were even more lipolytic than pancreatic glucagon.
