Abstract

Glycogen from a male child suffering from type IV glycogenosis was debranched with bacterial isoamylase and fractionated on Sephadex G 50. The unit chains, set free by the isoamylase, emerged as a single peak, similar to that for normal human liver glycogen, but of higher average chain length. The pattern of the unit chains was distinctly different from that shown by amylopectin, which displays 2 populations of unit chains. It is thereby reaffirmed that, contrary to previous belief, type IV glycogen is not amylopectin like in structure, and the name 'amylopectinosis'' for this disease is inappropriate.
