Polypeptides ultraviolet absorption spectra

VIII. The Ultraviolet Absorption Spectrum of the Peptide Bond and of the Polypeptide Fabric. 352... [Pg.319]

The detection of optically active absorption bands is usually prevented by technical barriers, for they generally lie in the far ultraviolet region of the spectrum. Yet, largely as a result of instrumental improvements, the first measurements of Cotton effects associated with helical polypeptides have very recently been achieved. Simmons and Blout (1960) first measured a minimum in the rotatory dispersion of tobacco mosaic virus protein at 232... [Pg.421]
