Abstract

The present study was undertaken to determine whether the alteration in amino acid distribution between the plasma and cellular compartment of the blood, previously described in dietary-obese rats, also occurs in genetically obese mice. The blood concentration of individual amino acids and its distribution between plasma and cells of lean and genetically obese mice (ob/ob) have been measured. The results demonstrated that genetically obese mice showed a decrease (55%, P = 0.0489) of free amino acids in the blood cells. Most amino acids were affected and among the most noteworthy characteristics was the observation that the reduction in concentration was more pronounced for the total concentration of the essential amino acids which was reduced by 76% (P = 0.0112) compared to cells of lean mice. These results suggest that an altered amino acid distribution between plasma and blood cells is a consequence of both diet-induced and genetic obesities.
