title: Some precursors of glycogen in Ascaris suum females.
abstract: Intensity of incorporation of the labelled carbon from glucose, glucosamine and leucine into the glycogen of somatic cells and reproductive organs of Ascaris suum females has been studied. Glucose was most intensively incorporated into the growing oocytes and into the uterine epithelial cells, whereas its incorporation into muscle glycogen was found to result in lowest rates. Radiocarbons from glucosamine and leucine were incorporated into tissue glycogen of female worms much less than glucose. Incorporation of isotopes into glycogen of the eggs depended on the formation of their primary shells. The ways of incorporation of isotopes into glycogen of the eggs after formation of all the shell layers are discussed.
