Superoxide dismutases (SOD) of high purity have been obtained from grey and white matter of bovine brain cerebral hemispheres. The SOD obtained have been shown to have three isoenzymes (a, b, c). A study of the catalytic and macromolecular properties of the SOD obtained from grey and white matter of cerebral hemispheres as well as their optical and electron paramagnetic resonance spectra indicates that both proteins possess similar properties. The possible function of SOD in grey and white matter of brain is discussed.

Cytochrome c from grey matter of brain has been obtained as a homogeneous preparation by electrophoresis on polyacrylamide gel and following electrofocusing in ampholine solutions. Its molecular weight, content of iron, redox potential and isoelectric point have been established. The absolute spectra of its oxidized and reduced forms are presented. Cytochrome c of brain cortex is similar in its properties to that obtained from other animal tissues as the heart and adrenal cortex.
