Biochemists investigate how molecular structure determines biological function, how molecules recognize each other and how the dynamic chemical changes that occur inside cells are orchestrated. Biochemists look at how living organisms function at the molecular level, studying such subjects as the structure of enzymes, protein folding, the transfer of genetic information or photosynthesis. The biochemistry major at Ohio State offers excellent training in the chemical basis of life and insight into the chemistry of living systems. The biochemistry major consists of a minimum of 12 upper-level courses in biochemistry, molecular genetics, organic and physical chemistry, and mathematics. Several science and mathematics courses are taken in support of the degree. These courses provide a strong foundation in all the scientific disciplines upon which biochemistry is built. All biochemistry majors take calculus, one year of general chemistry, one year of physics and one year of introductory biology. These basic math and science requirements of the biochemistry major are nearly identical to the requirements of many other science-based disciplines and can help fulfill prerequisites for pre-medicine, pre-optometry, pre-dentistry and pre-veterinary medicine.<br><br>Students can pursue either a Bachelor of Science or Bachelor of Arts in biochemistry. The BS is designed for students who wish to become professional biochemsists or to enter biotechnology fields. The BA includes all BS major requirements except for Calculus III, a second organic chemistry lab and a second physical biochemistry course, it also allows students to take algebra-based physics course work instead of the calculus-based physics course work required of the BS. This allows flexibility for the BA student to take other advanced science courses to prepare to apply to professional programs such as medicine, veterinary medicine, optometry or pharmacy.
