If you are looking for a good biochemistry text book for an introductory course in biochemistry, this book is highly recommended. Even though Lehninger passed away years ago, his famous book "Principles of Biochemistry" has stood as one of the best. Drs. Nelson and Cox from U of Wisconsin had updated this text 7 years ago when the second edition of the text was published. I used this text in my first year biochemistry class and I found that it was really help me learn this complicated yet fasinating materials. In 2000, the 3rd edition of text , still written by Nelson and Cox, is available in the market. I look through the book and I find that this book has been thoroughly updated while maintaining the excellent organization of the ordinary text. The CD-ROM is also included in this edition and there are lots of wonderful pictures and animation that can help you teach and learn biochemistry. Unlike Voets' text, this book is not chemistry oriented. So if you are looking for mechanism behind the metabolic process, Voet&Voet can serve as a better one. However, if you want to learn or teach biochemistry in general...this book is a book of your choice.
