Abstract
From measurements of glucose uptake by rat adipocytes, values of K (half-saturation constant) and V (maximal uptake at saturating glucose concentrations) are calculated. Insulin increases glucose uptake. Mannose and 3-O-methylglucose inhibit uptake. Different cell preparations give different values for K, V and insulin sensitivity. The possible effect on these differing parameters of adipocyte triglyceride content is considered. However the non-linearity of some double-reciprocal plots and certain correlations between the various kinetic parameters lead to the suggestion that rat adipocytes may have two systems for glucose uptake.
