BS in Biochemistry

The BS in Biochemistry is intended for those with an interest in the chemistry of living systems. It is an interdepartmental major for students interests in the chemistry of living systems, and is offered jointly by the Department of Chemistry and the Department of Biology.

Program Requirements and Policies

  • Sixteen courses and their accompanying labs are required to complete the major.
  • No major course may be taken Pass/Fail.
  • If you have more than one major, please see Bulletin for rules on double-counting courses across majors.
  • If you have a minor, no more than two course credits used toward the minor may be used toward foundation, distribution, major, or other minor requirements.
  • Note: A student majoring in biochemistry no longer needs to complete biology or chemistry research to be eligible for a summa cum laude degree.

Course Requirements

Chemistry Courses

  • Chemistry 1: Chemical Fundamentals w/lab OR Chemistry 11: General Chemistry 
  • Chemistry 2: Chemical Principles w/lab OR Chemistry 12: General Chemistry
  • Chemistry 31: Physical Chemistry I*
  • Chemistry 43: Bioanalytical Chemistry (Recommend) OR Chemistry 42: Quantitative Analysis)
  • Chemistry 51: Organic Chemistry I
  • Chemistry 53: Organic Chemistry I Lab
  • Chemistry 52: Organic Chemistry II
  • Chemistry 54: Organic Chemistry II Lab
  • Chemistry 171: Biochemistry I

Biology Courses

  • Biology 13: Cells and Organisms**
  • Biology 15: Cells and Organism Lab**
  • Biology 41: General Genetics
  • Biology 50: Experiments in Molecular Biology or Biology 54: Molecular Genetics Project Lab or Chemical & Biological Engineering 163: Recombinant DNA Technology ***
  • Biology 105: Molecular Biology

Other Required Courses

  • Math 34: Calculus II*
  • Physics 2: Introduction to Physics II w/ Lab or Physics 12: General Physics II w/ Lab

* The Biochemistry major requires Chemistry 31: Physical Chemistry, which has Math 34 and Phys 2 as prerequisites. Thus, the timing for completion of Math 32, Math 34, Phys 1 and Phys 2 (or their equivalents, such as AP credit) is flexible, but must be completed in the first three years.

** Starting with the incoming class of 2027, please note that BIO 13 and 15 are linked and should be taken concurrently. If you are an A&S student, both courses must be added to your SIS cart when enrolling in BIO 13 & 15. Engineering students should be aware that only a select few are permitted to enroll in this course.

*** The Bio 50 requirement can be fulfilled with Bio 50, Bio 54, ChBE 163, or a graded independent research course. Bio 50 is offered during the Fall semester of academic year. ChBE 163 is a summer course. Bio 54 is offered in the Spring semester of the academic year. Bio 54 will be limited to freshman, sophomores and juniors starting 2024. Therefore, seniors should not plan on taking it spring of their senior year to fulfill the Biochemistry lab requirement.

To fulfill the Bio 50 requirement, independent research must: 1) include a graded research-for-credit course such as Bio193 and Chem82 (but not Chem81), 2) involve molecular or cellular biology, and 3) be pre-approved.

To apply for the substitution, please prepare a one-page document with the following information:

  • A summary of the research project and progress made (or expected to be made) during the graded semester(s) (no more than 200 words).
  • A list of the research course(s) taken, grade(s) received, number of weeks worked each semester of graded research, and an average hours per week worked. If you are registering for research-for-credit for an upcoming semester, please list the course number and the expected number of hours per week.
  • A bulleted list of techniques/procedures you personally performed (or will perform) as part of this research. No details are necessary, just list the names of the different methods. Note that you can list all techniques you have performed over the course of this research project, not just the ones you performed (or will perform) during the graded semester.

Please send the document to your Principal Investigator. The PI should read the document and provide feedback if necessary. Once the PI approves of the document, the PI should send it to Prof. Mace with their approval that the statement is accurate. You are encouraged to send this document before the semester in which you are doing research, in order to get pre-approved that your planned course of research indeed qualifies for the Bio50 substitution. For questions about pre-approval, please email Prof. Mace at charles.mace@tufts.edu
