More and more researchers are discovering that many diseases are caused by biochemical deficiencies or defects. That is, instead of indicating that a disease is caused by a nutritional deficiency, researchers recognize that an underlying cause may be a single molecular structure within a cell that fails to turn a […]

The purity of cytochrome c can be evaluated by the ratio of the molar extinction coefficient (129.1 mM-1cm-1) at 416 nm of the reduced cytochrome c and the molar extinction coefficient (23.2 mM-1cm-1) at 280 of the oxidized cytochrome c. You extracted cytochrome c from yeast in the laboratory and […]
