Effects of Insulin, Tolbutamide, and Glucagon on Activities of Jejunal Carbohydrate-Metabolizing Enzymes in Humans.

摘要

In normal men insulin increases the activity of jejunal pyruvate kinase and hexokinase, decreases the activity of fructose diphosphatase and had no effect on fructose diphosphatate aldolase, while glucagon had opposite effects. Tolbutamide acted the same as insulin with the exception that it increased fructose diphosphatate aldolase activity. (Author)
