Abstract
Summary
1. Frozen and dried sections of adult and fetal liver were studied by infrared spectroscopy. 2. The infrared absorption band found at 9.70-9.60 ν is definitely assigned to glycogen. 3. Differences of location of this band in adult and fetal liver are discussed. 4. A spectroscopic method for semiquantitative estimation of glycogen in liver sections is described. 5. Relative glycogen content in adult and fetal liver under various nutritional conditions is reported. 6. Studies of liver glycogen after x-ray irradiation show the existence of an “acute” and “delayed” effect, the former decreasing, and the latter increasing liver glycogen.
