CSU San Marcos offers a program of courses leading to a Bachelor of Science in Biochemistry. Biochemistry focuses on the atomic and molecular level principles of chemical reactions in living systems. It is involved with elucidating the structure and function of biological molecules that control the basic processes in living organisms. It therefore plays an important role in understanding the chemical causes of disease, the development of medicines to control and cure illnesses, and the development of safe food supplies. Biochemistry majors are needed to help solve some of society's most difficult technological problems through research, development, and teaching.
