Spring 2020: COVID-19 Chemistry and Biochemistry Department Important Information

Lab Class Offerings: 

There will be NO in-person courses offered in SP20. All courses will be taught remotely, including lab courses. 
CHEM 7L, 7LM, 43A, 100A, 105A, 108, 100B, and 143B will continue to be offered in SP20 and will be taught remotely. That said, if you are not aiming to graduate in SP20, we would encourage you to consider revising your course plans to defer your enrollment in lab courses until the following academic year (or summer) so that you may benefit from the valuable hands-on experience gained from in-person lab courses. 
Lab Administrative Drops:

There will be no administrative lab drops, meaning you will not be automatically dropped from your lab course during week one for not attending your first lab meeting. Students will still be required to complete the Lab Safety Exam; however, students who do not pass the Lab Safety Requirement will not be administratively dropped in SP20. Please instead consult with your course instructor regarding the policy and consequence to your course grade regarding the Lab Safety requirement. 

Lab Fees: 
All lab course material fees will be cancelled in SP20. If you have already been assessed a fee, campus will be processing a reversal. 

Lab Waitlist:

Please note, we are NOT allowing further enrollments in CHEM 7L, 7LM, 43A, 100A, 105A, 108, 100B, and 143B for Spring 2020. If you are on the waitlist for any of these courses, please plan to complete the course in a future quarter. 

CHEM 123 (Spring 2020)

Space in CHEM 123 is limited. Most seats are saved for graduating Molecular Synthesis seniors. If you were planning to take this course to fulfill a lab elective, we highly recommend choosing another lab (e.g. CHEM 100B or CHEM 108). For any questions, please contact us through the Virtual Advising Center (VAC).

2019-2020 Announcements

Effective Fall 2019: CHEM 126A and CHEM 126B

Effective FA19, CHEM 127 and CHEM 126 have been renumbered to CHEM 126A and 126B, respectively.  There is a change in the courses such that they are now required to be completed sequentially, and the pre-requisites have changed such that MATH 10C and PHYS 1C are accepted (in addition to CHEM 6C/6CH, MATH 20C, and PHYS 2C). Please see below for the full details. In the 2019-2020 academic year, each course will only be offered once: CHEM 126A in FA19 and CHEM 126B in WI20.

CHEM 126A (previously 127), Physical Biochemistry I: Thermodynamics and Kinetics of Biomolecules

This course covers thermodynamics and kinetics of biomolecules from fundamental principles to biomolecular applications. Topics include thermodynamics, first and second laws, chemical equilibrium, solutions, kinetic theory, enzyme kinetics. Prerequisites: (CHEM6C or CHEM6CH) and (PHYS1C or PHYS2C) and (MATH10C or MATH20C)

CHEM 126B (previously 126), Physical Biochemistry II: Quantum and Statistical Mechanics of Biomolecules

This course covers quantum and statistical mechanics of biomolecules. Topics include quantum mechanics, molecular structure, spectroscopy fundamentals and applications to biomolecules, optical spectroscopy, NMR, and statistical approaches to protein folding. Prerequisites: CHEM126A or CHEM127.


Effective Fall 2017: Organic Chemistry Renumbering

CHEM 140A, 140B (BH), 140C (CH), 143A and 143AM have been renumbered to CHEM 40A, 40B (BH), 40C (CH), 43A and 43AM, respectively. For more information on this change, please visit our FAQ page.
