THE CARBOHYDRATE COMPOSITION OF THE GLYCOGEN BODY OF THE CHICK EMBRYO AS REVEALED BY PAPER CHROMATOGRAPHY

Abstract

Glycogen was extracted from glycogen bodies of 19-day chick embryos with KOH and absolute alcohol, and hydrolyzed in H₂SO₄. The hydrolysate was analyzed for carbohydrates by means of paper chromatography, using known carbohydrates as controls. Special techniques are described which were employed in the preparation of the hydrolysate and for chromatography. The carbohydrate of the glycogen body was identified as glucose. Evidence is presented to suggest that the polysaccharide stored by the glycogen body of 19-day chick embryos consists of glucose and not other carbohydrates.
