Second derivative Fourier transform infrared spectra of the proteins ribonuclease A, hemoglobin, and beta-lactoglobulin A (native and denatured) have been obtained in deuterium oxide solution from 1350 to 1800 cm-1. The relationship of the original spectra to their second derivatives is briefly discussed. In the second derivative spectra, clearly resolved peaks are observed which can be associated with the alpha-helix, beta-strands, and turns. No protein spectra with such resolution have… CONTINUE READING
