Autumn Term 2009
Introduction to Biophysical Chemistry
“Introduction to Biophysical Chemistry” emphasizes transport phenomena (molecular
diffusion, passive and active transport across membranes), methods for the separation and
characterization of macromolecules (electrophoresis, sedimentation equilibrium), treatment of
the interaction of light with matter (absorption, emission, scattering), methods of identification
of macromolecules (absorption spectroscopy, mass spectrometry), methods of structural
determination of macromolecules (light, x-ray, and neutron scattering from solutions of
macromolecules; x-ray diffraction; multiple-dimension NMR, EPR, linear and circular
dichroism, optical rotatory dispersion, and fluorescence resonance energy transfer), and
enzyme kinetics (catalysis and inhibition, rapid and ultrafast kinetics). The concepts and
mathematical manipulations will be illustrated with biochemical and biophysical applications.
This material is covered in Chapters 5−12 and 15–16 of the textbook by K. E. van Holde, W. C.
Johnson, and P. S. Ho.

Class Hours
This course (3 credits) tentatively meets Wednesdays and Fridays from 10:00 a.m. to 12 noon on
Wednesdays, 10:00am to 11:00am on Fridays, Room A507, Institute of Chemistry. There will be
recitation sessions approximately every two/ three weeks, according to the attached class
schedule. The recitation sessions will focus on the elaboration of complex concepts and subtle
points made during the lectures, as well as solving the types of problems that will appear on
problem sets and exams. You are strongly encouraged, if not expected, to attend ALL the
lectures and recitations.

Required: Kensal E. van Holde, W. Curtis Johnson, and Pui Shing Ho, “Principles of Physical
Biochemistry” (Second Edition 2006), Pearson Prentice Hall, Upper Saddle River, New Jersey.

Life Sciences”, Benjamin Cummings Publishing Company, Inc., 1979.
Grading
There will be a midterm and a final examination. Your grade is based on: homework (40%),
midterm (30%), and final (30%). To encourage class and recitation participation (attendance,
questions, comments, etc.), a bonus of up to 10% will be added to your final grade based on
your participation, prorated according to your actual attendance. A problem set will be due
approximately every two weeks. If you fail to obtain a copy of a homework set when it is
handed out in class, you may download it from the course website. The midterm and final
exams will not be found on the course website.
Completed assignments and midterm exams should be handed in during class hours, unless
alternative arrangements are made with Dr. Steve Yu. Graded homework and exam papers will
also be returned in class. Outside of class hours, you may pick up graded assignments from
Joseph Huang. Please staple all work.

Problem Sets
Homework will be handed out during class/recitation on a Friday (see schedule) and usually
due 12 days later on Wednesday by 10:00 a.m. Solutions will be given out by Friday of the same
week. Late assignments will be accepted, with the following penalties for a 100-point
assignment:
30% if turned in by Thursday 10:00 a.m. following the Wednesday due date;
50% if turned in by Friday 10:00 a.m. following the Wednesday due date;
70% if turned in by Monday 10:00 a.m. the following week;
90% if turned in by Tuesday 10:00 a.m. the week later;
100% if turned in after Wednesday 10:00 a.m. of the second week.
All homework must be turned in. Failure to do so will result in a grade of “F” or “I”.
