title: Properties of ATPases and energy-rich phosphates in erythrocytes of young and old individuals.
abstract: In the erythrocytes of individuals below 30 and above 60 years of age, the activities of several ATPases, the contents of ATP, ADP and AMP as well as the concentration of sialic acid on the erythrocyte membrane were measured. All parameters decreased with the sole exception of AMP which increased with age.
