摘要
The reasons for the occurrence of trace amounts of glucosamine in animal liver glycogens have been explored. Human liver glycogen is now shown to contain this amino sugar. Galactosamine, known to be the source of the incorporated glucosamine, is found to give rise to glucosamine in glycogen when administered orally, or as the N-acetyl derivative. The rabbit can also incorporate glucosamine into kidney glycogen but not into glycogen in heart or skeletal muscle. These experiments led to the discovery that glucosamine is incorporated into rabbit liver glycogen in such a way that there is intermolecular heterogeneity in the content of glucosamine, suggesting that there exists more than one pool of liver glycogen.
