Relationship between Age and Enzymatic Activities in Human Erythrocytes from Normal and Fava Bean-sensitive Subjects*

This paper is concerned with the relation between metabolic behavior and cell age in erythrocytes of normal subjects and in erythrocytes of fava bean-sensitive subjects in the nonhemolytic, the hemolytic, and the posthemolytic periods. That as red cells age there is a progressive decrease in the activity of several enzymes has been well established in vivo. The relationship between the age of erythrocytes and their enzy
