"Biophysics and Physiology of Carbon Dioxide" ed. by Christian Bauer, Gerolf Gros, Heinz Bartels

This volume contains the scientists's papers of various disciplines including biophysicists, chemists, biochemists, physiologists, pharmacologists, as well as clinicians whose research activities are cen tered around the various aspects of the reactions and the regulatory role of CO within the body.

This volume is dedicated to the biochemistry of carboxylation and decarboxylation reactions.
Particular emphasis was placed on the following subjects:
1) Chemical reactions of CO in water and facilitated diffusion of CO2,
2) CO adducts to proteins, in particular hemoglobin, and peptide 2 hormones,
3) structure and function of carbonic anhydrase,
4) CO2 exchange and carbonic anhydrase activity in respiratory and nonrespi ratory systems.
