Notizen:
The far-infrared absorption spectrum (40-400 cm-1) of solid pellets and films of several globular proteins (lysozyme, myoglobin, hemoglobin, serum albumin, ribonuclease, chymotrypsinogen, subtilisin) and of some representative polypeptides [nylon 66, poly (γ-benzyl L-glutamate)] have been investigated by using a Michelson interferometer. While polypeptides are known to present several peaks which can be assigned mostly to hydrogen-bond modes, all the investigated globular proteins display only one broad, intense baud in the 100-200 cm-1 region. The origin of this band, which persists even after denaturation or partial digestion, is discussed.
