Text: There is NO required text for this course. Exams and assignments will come entirely from class notes. The bookstore has the following recommended texts:

Chemical Approaches to the Synthesis of Peptides and Proteins, P. Lloyd-Williams, F. Albericio, E. Giralt, CRC Press, Boca Raton,1997. ISBN 0-8493-9142-3

An Introduction to Enzyme and Coenzyme Chemistry  (2nd ed),Tim Bugg, Blackwell Science, Oxford, 2004, ISBN: 1-4051-1452-5

Nucleic Acids in Chemistry and Biology (3rd ed), G. Michael Blackburn, Michael J. Gait, David Loakes, and David Williams, Royal Society of Chemistry Publishing, 2006, ISBN: 978-0-85404-654-6

Bibliography and suggestions for further reading

Exams: Two mid term exams and a Final. The dates of the midterm exams are Thur. Sept 25 and Tue., Oct. 30.

The Final Exam is scheduled for Wed., Dec. 17, 2008 at 9:00-11:00 am in SC 5502. No Alternate Final will be offered.

Please make your travel plans accordingly.

Grading: Each exam with count equally toward the final grade. Graduate students are also required to write a short paper (10 page limit) on a topic of their choice (with approval from me), related to bioorganic chemistry. In addition, they will present a short lecture (15 minutes) on their topic. You should choose a topic by Oct. 30.



Questions & Answers Page: I am posting questions and answers from the class, sent to me via email.
