Deuterium Exchange in Polypeptides
OBSERVATIONS on the rate of deuteration of the NH groups in solutions of proteins in heavy water (see, for example, ref. 1) have shown that in some proteins there is both a fast and a slow exchange, and it has been conjectured that those NH groups which exchange slowly are hydrogen-bonded in α-helix...
