Progress in biological and biochemical research is based mainly on a better understanding of life processes on a molecular level. Modern chemical techniques for structural elucidation even of sophisticated biomolecules and theoretical and mechanistic considerations help us to understand structure-function relations, metabolic processes, molecular and cellular recognition, and the reproduction of life. This series, Bioorganic Chemistry Frontiers, will bring together critical reviews on the progress in this field.

Better understanding of life processes on a molecular level is the aim of Bioorganic Chemistry. Structure elucidation, synthesis of biomimetic models, theoretical and mechanistic concepts e.g. of enzyme action are the basic tools. The new series will bring together critical reviews on the progress in this field.
