Ergebnisse der Enzymforschung

Nature volume 140, page 563 (02 October 1937) | Download Citation



THIS year's volume of the "Ergebnisse" deals in the main with the remote sections of the subject and to that extent is of special rather than general interest. Inasmuch as progress on the experimental side depends on the development of new technique, some of the contributions are of importance. For example, two Indian investigators in Bangalore deal with the application of dilatometry to enzyme reactions, which involves the measurement of volume changes under carefully standardized conditions. Though the mechanism through which volume change is caused is not clearly understood, it is claimed that the validity of its application has been established in specific cases by a comparative and critical study. The practical difficulty is to be sure that the reaction, or rather mean result of possibly several reactions measured, is the one which the experimenter describes.
