[Activity of NAD- and NADP-containing enzymes and catalase in human erythrocytes after sucrose loading]

The dynamics of glucose content and activity of GL-6-FDG, MDG, ICDG and of catalase in the erythrocytes of healthy people under glucose load was investigated. It has been established that maximal increase of the glucose content in blood under glucose load occurs 60 min later and the peak of activity of all the studied enzymes--90 min later. A degree of the activity increase in certain enzymes is not the same. It enhances considerably in GL-6-FDG and catalase and is hardly tracable in MDG and ICDG. A conclusion is made that glucose metabolism in erythrocytes is accompanied by the intensification of synthesis and hydrogen peroxide decomposition processes.
