Primary Hydrogen Isotope Effects
1978The important relationship between enzyme catalysis and the enhanced affinity of an enzyme for its substrate in the transition state was first noted by Pauling in 1948.(1) In recent years, attention has been focused on the design of stable analogs of transition states of enzyme reactions, since the structure of high-affinity analogs can provide ...

Solvent Hydrogen Isotope Effects
1978Biological and biochemical processes are affected by the partial or complete replacement of solvent protium oxide (H2O) by deuterium oxide (D2O) (1) Although some very simple organisms (certain algae, bacteria, etc.) have survived complete replacement of protium by deuterium, differences in morphology and metabolism are very apparent. Not surprisingly,

Hydrogen, known affectionately yet confusingly as “the proton” to NMR spectroscopists, can be regarded as the mother nucleus of high-resolution study. Its place and contribution to organic chemistry are well documented and its use is extensive, both because of its early emergence in the commercial spectrometer world and because it is the most sensitive,

Secondary Hydrogen Isotope Effects
1978Encouraged by the vast amount of knowledge gathered in years of study of all types of chemical catalysis and armed with the plethora of information available concerning chemical reactions of every conceivable nature, scientists have recently begun to explore the most elegant of all catalytic systems—enzymes.
