ENZYMATIC HYDROLYSIS OF GLYCOGEN AND DETERMINATION OF GLUCOSE
Hydrolysis converts glycogen from a non-reducing substance into reducing substances Hydrolysis of the glycogen molecule with acid results in splitting of all its glyosidic bonds giving only glucose molecules as the product Enzymes are more specific in the bond type they split |

What are the products of enzymatic hydrolysis of glycogen?
ENZYMATIC (FTom the Department HYDROLYSIS OF GLYCOGEN. of Toronto, Toronto, BY A. D. BARBOUR. of Biochemistry, University Canada.) (Received for publication, August 26, 1929.) The products of the enzymatic hydrolysis of glycogen have been assumedin the past to be maltose and glucose arising from intermediate dextrins and maltose.
Which enzyme initiates glycogenolysis?
Glycogenolysis is initiated by the action of a specific enzyme called phosphorylase, which yields glucose-1-phosphate. Glucose-1-phosphate is an important compound at the intersection of several metabolic pathways, such as glycolysis, glycogenesis, glycogenolysis, and gluconeogenesis.
Does hydrolysis inhibit the synthesis of glycogen?
Since the products of hydrolysis inhibit the process, it was thought that in solutions containing a sufficient concentration of the trisaccharide and enzyme, it might be possible to attain the enzymatic synthesis of glycogen, as has been done in the case of protein. Nevertheless, under these conditions synthesis did not occur.
What is the role of glycogenolysis in carbohydrate metabolism?
Glycogenolysis, along with glycolysis, plays a central role in carbohydrate metabolism. Glycogenolysis is the principal route of glycogen utilization. Glycogen is a storage polysaccharide consisting of D-glucose residues.
