The effect of UV radiation on the spectral characteristics of human nitrosohemoglobin in a wide dose range (151-4530 J/m2) was studied. It was shown that the irradiation of hemoprotein solutions with low doses of UV light (151-453 J/m2) led to local conformational rearrangements of the iron porphyrin moiety of the molecule. The apoprotein exhibited a high photostability under the conditions of the experiment. High doses of UV radiation (1359-4530 J/m2) induced the accumulation of methemoglobin in the protein sample. A scheme of the photoinduced formation of methemoglobin was elaborated.

D012996 Solutions The homogeneous mixtures formed by the mixing of a solid, liquid, or gaseous substance (solute) with a liquid (the solvent), from which the dissolved substances can be recovered by physical processes. (From Grant & Hackh's Chemical Dictionary, 5th ed) Solution
D014466 Ultraviolet Rays That portion of the electromagnetic spectrum immediately below the visible range and extending into the x-ray frequencies. The longer wavelengths (near-UV or biotic or vital rays) are necessary for the endogenous synthesis of vitamin D and are also called antirachitic rays; the shorter, ionizing wavelengths (far-UV or abiotic or extravital rays) are viricidal, bactericidal, mutagenic, and carcinogenic and are used as disinfectants.
