Molecules in E. coli (as in the BIS102-03 Handout Book)
Acid/Base Tutorial (similar to the one in the BIS102-03 Handout Book)
Amino acid properties.
3-D Structure Pages and Sites
The following sites include "live" 3-D structures and tutorials on a variety of biological molecules

**Examination of 3-D structures requires the the Chime plug-in which is available from MDL Information Systems, Inc. Click on the Chime link to download the plug-in for Macintosh or Windows computers before accessing these sites ( Chime should already be on all UCD computers, if it is not on a computer you use contact Dr. Gasser so he can have it fixed). Chime works best with Netscape Navigator 3.01 or higher).**
Dr. Gasser's amino acid structures site at U. C. Davis.
(jump straight to an amino acid by clicking on the one letter code below!)

G, A, V, L, I, P, F, Y, W, S, T, N, Q, C, M, D, E, H, K, R

For another view of amino acids look at Dr. William McClure's excellent Amino Acid Models site at Carnegie Mellon University (a part of Molecular Models for Biochemistry at CMU).
Protein structure can also be examined at Dr. McClure's site.
Myoglobin and Hemoglobin can be examined in detail on Paul Reisberg's excellent Biochemistry pages at Wellesley College.
Learn about serine proteases by exploring the structure of chymotrypsin at this site set up by Dr. Gasser at U. C. Davis.
Dr. Gasser's MCB121 Structure Pages have live structures of DNA, regulatory transcription factors, and TATA-binding factors.
Finally, essentially all known structures are available at Molecules R Us, a wonderful web site set up by the National Institutes of Health.
