[Hormonal activity control of liver glycogen phosphorylases with special reference to their significance within the scope of a stress reaction].
For the mechanism of glycogen metabolism in the liver hormonal action of epinephrine, norepinephrine, glucagon, vasopressin and angiotensin II is of importance. The potential importance of hormonal regulation for interpreting the changes in glycogen metabolism under conditions of stress is underlined. Own results show an acute increase of glycogen phosphorylase activity in stress within 1-2 minutes. 24 hours fasting decreases the sensibility of this enzyme towards the hormonal influence.
