Developmental Changes of Guanidino Compounds in Chick Embryo
It is well known that many kinds of guanidino compounds are observed in invertebrates and vertebrates1,2. The appearance of guanidino compounds in animals is thought to be related to nitrogen metabolism but there are no reports concerning guanidino compounds and embryogenesis. The present study was undertaken to learn about the appearance and changes in concentrations of guanidino compounds in the whole chick embryo, yolk and embryonic organs at various stages of embryonic development. It is hoped that this study might contribute to our basic understanding of guanidino compound metabolism during embryogenesis.
