Glycolytic Enzymes in Adipose Tissue of Adult Diabetics

The maximal activities of hexokinase and phosphofructokinase were measured in human adipose tissue. Though the mean activity of hexokinase was similar between a group of adult diabetics (n=24) and a group of non-diabetic controls (n=25), in the diabetic group the activity of phosphofructokinase was definitely reduced. Possibly this enzyme deficiency might contribute to impaired glucose utilization by the adipose cell in diabetes.
