Thank you for looking. This is a hardcover original edition, Fourth Edition, of Voet's Biochemistry. Unlike the Japanese version, it is bound in a single volume. There is overall scuffing, sticker residue on the back cover, damage to the corners, and some stains, but there appears to be no yellowing of the pages or writing.
