Further studies on high molecular weight liver glycogen
A simple method for the extraction of undegraded liver glycogen is described. The molecular weight distribution curve as measured by gradient centrifugation was quite variable and was found to be unrelated to glycogen content. The concentration of malto-oligosaccharides in liver was estimated by a n...
