In September and October 2007, I wrote some material on Enzyme Kinetics for a first-year Biochemistry course for the VU University Amsterdam. The document is in Dutch, and as I wrote it on my own initiative, I grant permission to use it freely under the terms of the Creative Commons (BY-NC-SA 3.0) License. There is also a version in black-and-white, useful for printing.

More recently, I wrote an entirely new reader for the course. This work was paid for by the VU University however, so it may not be used without permission.
