Program of Study


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.

With suitable choice of electives, this degree meets certification requirements of the American Chemical Society.

Program Student Learning Outcomes


Students who graduate with a Bachelor of Science in Biochemistry will be able to:

  1. Demonstrate their theoretical knowledge in the sub-disciplines of organic, inorganic, analytical, physical, and biochemistry.
  2. Employ scientific inquiry and modern instrumentation in the design, performance, documentation, and quantitative interpretation of laboratory experiments at a level suitable for a career in industry or entry into a graduate program.
  3. Retrieve and evaluate chemical information from the chemistry literature, and communicate this information in written, oral, and electronic formats using appropriate scientific language to both experts and the general public.
  4. Identify and assess molecular hazards, the impact of chemicals on human health and the environment, and describe the fundamental principles of green chemistry.
  5. Demonstrate advanced knowledge of the key principles (macromolecular structure, function, dynamics, and energy flow in living systems) of biochemistry.

Career Opportunities


The degree in Biochemistry prepares students to go into a variety of careers. Students are prepared for industrial careers in both the biotechnology and traditional drug development sector. In addition, the courses required for the degree meet the requirements for almost all medical, dental, optometry, pharmacy, veterinary, and other health-profession schools. The degree is also excellent preparation for graduate work in biochemistry or the biomedical sciences. Therefore, the completion of this degree program leaves the student with many possible career options (students wishing to pursue a career in a health profession should meet with the CSUSM pre-health advisor for specific requirements for professional schools in their area).

Since chemical principles are the basis for understanding biochemistry, each student will study the areas of organic, analytical, inorganic, and physical chemistry as well as biochemistry. In addition, students will take courses in molecular biology, and they will learn to use the most recent technology in instrumentation.

Preparation


Up to five (5) units of chemistry credit can be applied toward a B.S. degree in Biochemistry at Cal State San Marcos for students who have successfully completed the Advanced Placement Test in chemistry with a score of 4 or 5. It is recommended that students with a score of 4 or 5 on the AP Test in chemistry consider auditing CHEM 150  during the Fall semester in preparation for CHEM 162 .

Special Conditions for the Bachelor of Science in Biochemistry


With the exception of CHEM 100 , all courses counted toward the major, including Preparation for the Major courses, must be completed with a grade of C (2.0) or better. Transfer students must complete a minimum of 24 units counted toward the biochemistry major at CSUSM.

General Education (43 Units)


General Education Requirements  

Preparation for the Major (49 Units)


Note:


**Some courses supporting the preparation or electives in the major may satisfy the Mathematics and Science requirements of General Education. The courses fulfilling this double requirement are denoted by **.

Major Requirements (35 Units)


Upper-Division Science Elective (7 Units)


Note:


Or another science course with written approval from a Chemistry or Biochemistry faculty member.

*Course can be taken twice for a total of four (4) units.

Minimum Total (120 Units)


The minimum number of units required for this degree is 120
