| Abstract: | Some spectral properties of human thyroalbumin have been studied. Ultra-violet absorption of the aqueous solution of this protein has two maxima: at the wavelengths of 276 and 296--298 nm. Under the excitation by a monochromatic light with the wavelength of 280 nm the thyroalbumin has the fluorescence spectrum with the maximum at 430 nm and the quantum yeild of fluorescence about 5,4%. It has been established that thyroalbumin fluorescence consists of two components with the maxima at 385 and 450 nm. Moreover the "sortwave" component is principally attributed for by the presence do iodoamino acids. |
