Abstract/OtherAbstract:
A connecting link between carbohydrate and fat metabolism in adipose tissue is theconcentration of alpha-glycerophosphate derived predominantly from the glycolysis ofglucose entering the fat cell. However, several investigators have reported the presence of a glycerol specific kinase in the epidiymal fat-pad of the rat and obob mouse. This enzyme's presence in other mammalian adipose tissue could contribute to the alpha-glycerophosphate pool and thus affect both carbohydrate and fat metabolism within the fat cell. Glycerokinase was demonstrated in isolated fat cells obtained from the subcutaneous, perirenal, epididymal, and dorsal intrascapular brown fat depots of the adultmale rat. It was found to be particularly sensitive to in vivo lipogenic stimuli in both the subcutaneous and the brown adipose tissue and concluded that insulin is involved in adipose glycerokinase stimulation. Therefore, the main function of glycerokinase in normal adipose tissue may be to augment the anabolic action of insulin. It isfurther suggested that deviation from the normal control of this lipogenic enzyme couldlead to a gradual accumulation of fat and eventual obesity.
