title: Effect of Food Load on Activities of Enzymes of the Main Metabolic Pathways in Blood Lymphocytes in Girls with Different Anthropometric Parameters.
abstract: Changes in enzyme activities reflecting functioning of the basic metabolic pathways in cells (Krebs cycle, glycolysis, pentose phosphate pathway) were evaluated in blood lymphocytes of girls of different somatotypes with different body composition under conditions of food load. A common regularity was found: a decrease in succinate dehydrogenase activity after meal in girls of all somatotypes. Specific features of individual somatotypes were also revealed. Only girls of athletic somatotype showed increased lactate dehydrogenase level after food load. Activity of glucose-6-phosphate dehydrogenase increased (more than twice) after food load only in girls of euryplastic somatotype. This somatotype is characterized by maximum values of fat and other components of the body. Glucose-6-phosphate dehydrogenase is the first enzyme of the pentose phosphate pathway; activation of this pathway accompanies enhancement of synthetic processes, including lipid synthesis. This can contribute to accumulation of the fat component (and other components) due to redistribution of substrate flows between metabolic pathways.
