I almost tore this book into pieces from anger while reading it. This would have saved me tens if not hundreds of hours during my undergrad days as a biochemist. It covers all the main points, aspects, and principles in biochemistry and simplifies them in a summarizable way that can quickly teach newcomers what biochemistry is and serve as a strong refresher/reference/reminder for those specialized or graduated with a degree of biochemistry. I'm still angry why this book wasn't published before I majored in biochemistry in university. I demand compensation!!!!!
