title: [Changes in the characteristics of several carbohydrate metabolism enzymes during differentiation of loach skeletal muscle].
abstract: The gradual change of enzymes of glycogen metabolism proceeds during the skeletal muscle differentiation in the loach. The portion of the muscle type phosphorylase in the skeletal muscles of the embryo at the stage of the beginning of movement amounts to 30% and that at the stage of hatching to slightly over 50%. At the stage of yolk resorption, the skeletal muscles contain the muscle type phosphorylase only. At the same time the value of KM(UDPG) for glycogen synthetase gradually increases from 0,1 X 10(-3) up to 0,57 X 10(-3) M. The activity of alpha-glycerophosphate dehydrogenase increases more than 70 times.
