Biochemistry is the science concerned chiefly with the chemistry of biological processes. It attempts to utilize the tools and concepts of chemistry, particularly organic and physical chemistry, for elucidation of the living system. The science has been variously referred to as physiological chemistry and as biological chemistry. Biochemical analysis techniques refer to a set of methods, assays, and procedures that enable scientists to analyze the substances found in living organisms and the chemical reactions underlying life processes. The development of biochemical analysis techniques involves not only on advances in biochemistry, but also on progress in engineering and physics in order to rapidly translate an idea from the laboratory to the clinic.
