Glucagon immunoreactivity (IRG) was measured in plasma of 8 duodenopancreatectomized patients with antiserum 30-K. Arginine infusions failed to raise plasma IRG, whereas in control subjects IRG rose 3-fold. Column chromatography revealed that the basal IRG measured in these plasmas was not due to glucagon (molecular weight 3485) but to other plasma factors, mainly of high molecular weight. This suggests that diabetes mellitus does not require the presence of glucagon to produce the clinical picture, as suggested by other authors. Plasma levels of the amino acids alanine, serine, ornithine, and arginine were significantly (p less than 0.05) elevated, the former two being gluconeogenic substrates and the latter two constituents of the urea cycle. This amino acid abnormality may be a consequence of glucagon deficiency.

D005934 Glucagon A 29-amino acid pancreatic peptide derived from proglucagon which is also the precursor of intestinal GLUCAGON-LIKE PEPTIDES. Glucagon is secreted by PANCREATIC ALPHA CELLS and plays an important role in regulation of BLOOD GLUCOSE concentration, ketone metabolism, and several other biochemical and physiological processes.
