The effect of fructose on the glucose tolerance curve

Abstract
Fructose, when injected intraven., lowers the glucose tolerance curve of normal dogs, and also the glucose tolerance curve of depancreatized dogs receiving a steady supply of insulin. This effect in normal animals is evidently not due to a stimulation of the pancreas to give increased secretion of insulin. An hypothesis is advanced that fructose exerts a catalytic influence on the utilization of glucose, the site of this influence, probably, being in the glycogenesis mechanism of the liver.
