Résumé : In this paper, the limitations of electron microscopic techniques, as used for the study of molecular and macro molecular structures of the glycogen type, are defined. Different aspects of glycogen, as isolated from different tissues, were compared and examined ultrastructurally. The in vitro synthesis of glycogen and the changes in its structure, which are produced by enzymatically attaching additional glucose units to the particles, are discussed. Studies of the ultrastructural localization of the enzymes bound to the particles and the eventual role played by the membranes are described. It is concluded that on the membranes of the sarcoplasmic reticulum of the striated muscle a multi enzyme complex exists that consists of phosphorylase phosphorylase kinase and the primer.
