Program Requirements

The biochemistry major provides interdisciplinary training, education and experience in the chemical and biological sciences. Biochemistry focuses on understanding the chemical processes of living organisms,the reaction pathways that sustain life, the principles of how structure defines function, and the physical basis of biomolecular interactions. Â鶹ÒùÔº who major in Biochemistry are prepared for diverse careers in medicine, scientific research, biotechnology, pharmacy, biomedical consulting, teaching and education, among other professions. The undergraduate degree in Biochemistry emphasizes knowledge and understanding of:
 

  • Foundational principles of biology and chemistry

  • The building blocks of life (DNA, RNA and proteins), how they evolved, how they interact, and how organisms make and degrade these building blocks

  • How living organisms maintain homeostasis and regulate metabolism

  • The molecular mechanisms of how living systems respond to changes, such as environmental perturbations, disease, and chemical therapeutics

  • How chemical reactions impact human health

The undergraduate degree in Biochemistry also emphasizes and cultivates development of the following skills:
 

  • Quantitative problem solving

  • Critical thinking and analytical reasoning

  • Communication of scientific concepts and ideas

Because biochemistry connects to scientific disciplines ranging from genetics, human physiology, microbiology, neuroscience, cell biology, chemistry, and geology, Biochemistry majors are given the freedom to explore advanced electives in many of these subjects. Additional information about the Biochemistry B.A. can be found on the Biochemistry Department website.

Biochemistry major students are prepared for many different careers after graduation.  offers a number of programs and services designed to help students plan their career, including workshops, internships, and placement services after graduation. For an appointment with a career counselor or for more information, call 303-492-6541 or stop by Center for Community, N352.
 

Additional Opportunities

Undergraduate Research

Undergraduates are encouraged to participate in research to prepare themselves for graduate school, professional school, or industry. There are multiple opportunities for undergraduates to be involved in research within the Department of Biochemistry. For more information, visit our Departmental Undergraduate research page.

Study Abroad

The experience of studying abroad can prove invaluable. For information about study abroad programs, visit the  website.

Teaching Certification

Biochemistry majors can also earn certification as teachers through the School of Education. The program for a secondary school science-teaching certificate is challenging requiring a broad, strong background in science, as well as coursework in education and practice teaching. It usually requires at least five years of study. Â鶹ÒùÔº interested in teacher certification are encouraged to contact the .

Academic Planning:

Â鶹ÒùÔº who declared a biochemistry major before Fall 2017 should follow the requirements as listed in their audit.

Course pre-fixes were updated from CHEM to BCHM for several courses starting in Fall 2019. For questions or concerns about how these changes effect your degree status, please schedule an appointment with an Academic Advisor.

Grades

All required courses and ancillary courses must be completed with a grade of C- or better. In addition, the College of Arts and Sciences requires at least 30 hours of C- or better in the major and requires an average GPA of 2.00 or higher in all classes attempted in the major department.

Credit Hours

Â鶹ÒùÔº who do all their major courses at CU Boulder will more than meet the College requirements for the minimum total (30 credits) and upper division (18 credits) hours in the major.

AP, Advanced Placement in Chemistry

The following will be allowed for advanced placement in chemistry. Score of 5: credit for general chemistry 1 with lab (CHEM 1113 and 1114 or). Â鶹ÒùÔº may register for general chemistry 2 with lab (CHEM 1133/1134). Â鶹ÒùÔº should consult a departmental advisor before registering for a second semester general chemistry course.

IB, International Baccalaureate in Chemistry

The following will be allowed for IB-higher in chemistry. Score of 7: credit for general chemistry 1 and 2 with lab (CHEM 1113/1114 and 1133/1134).; students may register for CHEM 3311/3321 or 3451/3371. Score of 6: credit for general chemistry 1 (CHEM 1113/1114); students may register for CHEM 1133/1134. Â鶹ÒùÔº should consult a departmental advisor before registering organic chemistry or for a second semester general chemistry course.

Transfer Credits

Â鶹ÒùÔº may transfer courses in chemistry that are equivalent to courses given at CU Boulder but carry fewer credit hours. They must take sufficient courses in chemistry so that the total credits for graduation is at least 30. An academic advisor should be consulted regarding this type of deficiency.

Transfer Â鶹ÒùÔº

Transfer students should note that the College of Arts & Sciences requires at least 18 hours of upper-division credits in the major. Lower division courses at other institutions will transfer as lower division credit, even if the corresponding CU Boulder courses are upper division. For example, organic chemistry taken at a community college or as lower division at a four-year college will only carry lower division credit if it is accepted by the department to satisfy CHEM 3311, 3321, 3331, and 3341. A biochemistry major with such transfer credit will need to take additional upper division chemistry courses to complete the required 18 hours in the major and 45 upper division hours.

Transfer students who plan to complete a B.A. degree in the Biochemistry Department must complete at the Boulder campus a minimum of 12 credit hours of upper-division courses in chemistry covering at least 2 of the sub-disciplines in their major.  The sub-disciplines for a biochemistry major are organic, physical, and biochemistry. Course work to satisfy this minimum requirement may NOT include CHEM 4901 and must be completed after matriculation into the College of Arts and Sciences.

Undergraduate majors in the Biochemistry Department must plan their courses carefully since there are specific prerequisites for advanced courses that must be completed in an orderly sequence during the freshman through the junior years. In addition, the College of Arts & Science Core curriculum must be worked into the schedule. Suggestions for majors include:

  • Math should be started the first year and continued without a break.
  • Math courses are a serious hurdle for many biochemistry majors. It is much better to start Pre-Calculus Math 1150, doing a fair bit of review work, and earn A's or B's than to try Calculus l, (MATH 1300 or APPM 1350) and receive a D or F. Even students that have some calculus in high school may have difficulty with MATH 1300 if their algebra, geometry, and trigonometry backgrounds are weak. When biochemistry students fail to achieve a good grade record their first year at CU Boulder it is most commonly due to a weak math background.
  • Chemistry should be taken the first year, and should take precedence over general biology if biology is also required in the student's course work.
  • Â鶹ÒùÔº are very strongly advised against taking General Physics 1 until they have completed Calculus 1, and preferably both Calculus 1 and Calculus 2.
  • Most first year students should take no more than 16 hours per semester and preferably less. Â鶹ÒùÔº who are working may want to consider taking even fewer hours per semester. Taking 16 hrs/sem while working more than 20 hrs/week is likely to hurt academic performance.
  • Quality is better than quantity. Thus, undergraduates who complete a degree with a grade point average greater than 3.4 will have many job and graduate school opportunities even though they may have taken only 12-14 hours each semester. Whereas students who take 18-22 hours each semester, with a G.P.A. less than 3.0 while working 10 hrs/week, will find few or no graduate school openings. Â鶹ÒùÔº, who must work outside of school, should consider taking a lighter course load.
  • University study requires an intensive effort on a student's part for at least nine months a year. Â鶹ÒùÔº should therefore use their summers wisely. Summer may be a good time to catch up on coursework or credits; many required and elective courses are taught during summer school. On the other hand, many students find it advantageous to have a change of pace during the summer, and many need to earn some money. A chemistry-related job can be a great experience. Some large and small chemical or health-related companies hire undergraduates during summers. Career Services can be helpful in locating a suitable position. Some schools around the country have undergraduate research participation programs open to outside students. CU Boulder offers the Undergraduate Research Opportunity Program (UROP) and the Biosciences Undergraduate Research Skills and Training (BURST) program to a limited number of students.
  • The majors organic chemistry courses are also only taught once a year. Plan ahead for these courses. The elective course CHEM 4021 (Inorganic Synthesis Lab) is also taught only in the Spring semester. Most graduate courses are taught once a year, with a few taught every other year.
  • Â鶹ÒùÔº taking biology should realize that EBIO 1210/1230 are taught only in the Fall semester, and the second-semester biology courses, EBIO 1220/1240, are taught only in the Spring. The EBIO sequence is also taught during the summer.  The MCDB sequence is not taught in the summer.
