“…8). coloration depends on the chain length of a-1.4 glucosidic linkage of the end groups in polysaccharide (Swanson 1948, Takeuchi 1958, 1962, and also partly on the amount of primer glycogen (Iwamasa and Takeuchi 1972) . In general, polyglucose stained bluish with iodine is synthesized by higher phosphorylase activity and polyglucose having a tendency to stain reddish is usually synthesized by both phosphorylase and higher branching glycosyltransferase activities (Takeuchi 1962) .…”

During the investigation of the histochemical synthesis of glycogen particles from glucose 1-phosphate by the phosphorylase-branching glycosyltransferase system in various tissue cells, it was observed that focal synthesis localized in a certain area of the cytoplasm occurred in some cells. This differed from the usual synthesis in which particles of similar size were synthesized within the cytoplasm. Otherwise, cytoplasmic particles of various size were also synthesized in other cells under the same histochemical condition. The possible significance of the presence of these patterns in glycogen synthesis is discussed.
