Bioorganic chemistry is commonly described as the study of chemistry of living systems using the strategies and methodologies traditionally associated with organic chemistry. Recently, this fast moving sub-discipline has witnessed some very exciting results in applying design and synthesis techniques to the most difficult problems in molecular biology. Much of the current work in areas as: protein folding; signal transduction; molecular recognition; monoclonal antibodies; and drug design, is being conducted by bioorganic chemists. Bioorganic Chemistry: Peptides and Proteins is the second of the three text references being prepared (edited) by Sidney Hecht to service the needs of the many graduate students and researchers who have strong interest in this field.
