title: Change of pyrophosphatase activity in the chicken serum during the course of development.
abstract: The change of pyrophosphatase activity in the chicken serum was studied during the course of development. The enzyme activity was higher at the age of rapid growth than at the age of maturation. This finding suggests the participation of pyrophosphatase and pyrophosphate in controlling the calcification process.
