We isolated from beef liver a putativeinsulinmediator termed INS-2, 1. Its structure was determined to be a novel inositol glycan pseudo-disaccharide Mn(2+) chelate containing D-chiro-inositol 2a (as pinitol) and galactosamine. Purification methods were scaled up from those previously reported to isolate an inositol glycan with similar composition from rat liver.(1) Structure of the beef liver glycan
