...Glycogen. The $5,000 annual award of the Sugar Research Foundation went to Austrian-born Dr. Carl Cori of Washington University Medical School, St. Louis. Pale, tall Dr. Cori, 51, specializes in sugar, the basic fuel of human metabolism. For 20 years he has traced the progress of sugar through the body, watched it turn into glycogen (animal starch), measured how much glycogen is stored in the muscles and liver...
Died. Dr. Russell Henry Chittenden, 87, discoverer of protein, longtime director of Yale's Sheffield Scientific School (1898-1922); in New Haven, As a 19-year-old Sheffield senior, he was the first to isolate in living tissue a free amino acid, found in it the glycocoll and glycogen later famed as protein...
...Supercharger." Glycogen, a form of starch manufactured in the liver, is the substance which the body uses for quick energy. When glycogen is consumed, lactic acid is produced-mostly a waste product since a good part of it breaks down into carbon dioxide and water. But some lactic acid is reconverted into glycogen, which is then available for further energy release. Last week Dr. George Bogdan Kistiakowsky and five co-workers of Harvard compared this operation to that of a gasoline engine supercharger, which uses the energy of exhaust gases to pump air at high pressure into the firing cylinders...
First he pictures the living cell (normal or cancerous) and its system: 1) nucleus, 2) protoplasm, 3) semipermeable cell membrane, 4) environment (blood and tissue juices). From its environment the cell gets its energy-producing materials. Through its environment it gets rid of its wastes. Glycogen, or animal sugar, is almost the sole source of cell energy. In normal cells half the absorbed glycogen is oxidized, half turned to lactic acid. In cancerous cells, for every 13 glycogen molecules, twelve split up into lactic acid and one is oxidized...
