Here is a copy of Biochemistry by Christopher K. Mathews & K. E. van Holde of Oregon State University. I believe this was the free copy given to the university staff. Published in 1990. This has over 1100 pages of everything you ever wanted to know about biochemistry and even a few things you didn't want to know! The book is hardcover and is in reasonably good condition with only light wear. There is some damage to the bottom back outer corner from being dropped, however, this does not effect the book in any meaningful way. Pages are crisp and there are no dogears. The images are clean there is no sign of yellowing. There is a bit of pen ink on the bottom of the book pages. Free shipping in the lower 48 States. All others inquire for a quote.
