It is that branch of life science that deals with the study of biological processes using chemical methods.
[1] Protein and enzyme function are examples of these processes.
While biochemistry aims at understanding biological processes using chemistry, bioorganic chemistry attempts to expand organic-chemical researches (that is, structures, synthesis, and kinetics) toward biology.
Biophysical organic chemistry is a term used when attempting to describe intimate details of molecular recognition by bioorganic chemistry.
Compound discoveries have and often lead to medicinal uses, development of herbicides and insecticides.
