ABSTRACT

Background: No research has been reported about changes in plasma levels of amino acids after the administration of glucose or sucrose to young and aged men.
Objective: We want to know whether essential and non-essential amino acids are influenced by the administration of glucose or sucrose in the same way.
Results: Plasma levels of amino acids were measured after the administration of 50 grams of glucose or sucrose to young (18-22 years old) and aged (=50 years old) male adults. Plasma levels of total amino acids decreased after the administration of glucose. Decrease in the total amino acid levels was significant in aged men after the administration of sucrose. A significant decrease in plasma levels of total non-essential amino acids was observed at 120 min after the administration of glucose but not sucrose in both aged and young men. Both glucose and sucrose administrations resulted in a significant decrease in the plasma levels of the total essential amino acid levels and branched amino acids in young and aged men.
Conclusion: These results suggest that plasma amino acids, particularly essential amino acids, may be transported from the blood soon after the administration of sugar (glucose or sucrose) to the tissues, such as muscles, possibly due to an increase in the insulin levels.
