Lehninger Principles of Biochemistry, Loose-Leaf

Can't beat Lehninger if you want to know about Biochemistry. It's a bit dry, but what do you want from a textbook.

The book is good but it was not bound and i just found out that they will be using the sixth edition next semester.

I bought the Lehninger textbook of biochemistry and according to the seller it was described as good as new. What I have received is any thing but a book .
