Before you explore this one, read the author’s preface entitled  “Why Chemical Logic?” In it, he provides a rational explanation for his  arrangement of topics in teaching biochemistry and explains why they  differ from more modern presentations. The approach is interesting and  radical, starting with lipid structure and then moving to protein  structure, carbohydrate structure, DNA/genomics/proteomics, binding,  transport/kinetics, catalysis, oxidation/phosphorylation, and finally,  signal transduction. Each of these items is hierarchically organized  with subtopics that lead, via hyperlinks, to more information. On-line  textbook lovers will enjoy the way this is laid out with extensive text  descriptions interlaced with images as appropriate. After looking at the  site, I was impressed enough to rethink how I will teach these same  subjects in my own classes.
