[Effect of alcohols on photochemical transformations of mouse oxyhemoglobin]

The spectral method was used to study the influence of such alcohols as xylene, mannitol, sorbitol and dulcitol on photochemical oxidation of mouse oxyhemoglobin molecules (6.68 X 10(-5) M). Mannitol (5.35 X 10(-4) M) was shown to exert a protective action with regard to UV-irradiated hemoproteid: the extent to which oxyhemoglobin molecules were oxidized in the presence of mannotol was lesser than that in its absence. Sorbiol or xylene (5.35 X 10(-4) M) added to an aqueous solution of hemoproteid failed to exert a photoprotective effect with respect to protein molecules.
