Biochemistry is the study of the structure, composition, and chemical reactions of substances in living systems. Biochemistry emerged as a separate discipline when scientists applied the molecular approaches of chemistry to the vast variety of biological systems. Some biochemists study the most basic of life processes, such as the synthesis of DNA, which carries the genetic information, and the function of proteins, which can provide structure or catalyze biological reactions. Biochemists work with all sorts of organisms, from viruses and bacteria to plants and man. With knowledge of the basic molecular mechanisms, biochemists study how life processes are integrated to allow individual cells to function and interact to form complex organisms. Thus, the aim of biochemistry is to provide an understanding of every aspect of the structure and function of living things at the molecular level.

employ biochemists in research as well as in areas outside the lab such as marketing, management, science information, technical writing, and editing. Combined with a law degree, a B.S. in biochemistry is a good background for a career as a patent attorney.
