title: [Changes in glycogen metabolism in chick embryo liver in relation to the formation of glycosomes].
abstract: In the chick embryo liver the portion of granular glycogen increases from 15 to 90% of the total content during the period from the 8th till the 14th days of developments. The activity of glycogen synthetase (KF 2.4.1.11) localized in the fraction of granular glycogen increases from 40 to 90% of the total activity in the 18 days old embryo. The activity of phosphorylase (KF 2.4.1.1) is detected in the granular glycogen of the liver only on the 12th day of development (10% of the total activity) and increase up to 80% on the 19th day of development. The maximal activation of glycogen synthetase and phosphorylase is noted after the glycosomes of formation in the developing embryoliver. A suggestion is put forward to the effect that the process of glycosome formation is a factor of the control of glycogen synthetase and phosphorylase activity.
