There is no easy way to teach biochemistry, the subject is simply vast and atrociously detailed. However, textbooks can be a great asset to try to provide a big-picture view of the almost too-detailed molecular understanding of biochemistry. In this aspect, this book fulfilled its job. Since I did not use the exercises found at the end of the chapters, I cannot comment on their quality. However, as a reference material I found the book to be more than adequate. I would definitely recommend it to anyone seriously interested in biochemistry; however, it is not a light read by any stretch of the imagination.
Great book! I greatly appreciated the paragraphs that were given titles that reflected the topic in that paragraph. It helped to study: one could just read the title and consider re-studying the item or checking it off as "OK, I know that". My edition had an error in the DNA polymerases, which transpired during my exam. I suppose (hope) my professor passed it on.
