| Popis: | 1. 1. The pathways of serine biosynthesis utilizing either phosphorylated or nonphosphorylated intermediates, as well as the levels of activity of phosphoglycerate and d -glycerate dehydrogenases, have been investigated in tissues of frog at various stages of development. 2. 2. Serine biosynthesis occurs via the phosphorylated pathway in the unfertilized egg but by the nonphosphorylated route in liver of tadpoles undergoing metamorphosis and in adult liver. 3. 3. Phosphoglycerate dehydrogenase is present in unfertilized eggs and its activity remains relatively constant during the first the first 30 days following fertilization. Appreciable d -glycerate dehydrogenase activity is not detected until several days following hatching. |
