Год изд.:2003
Описание: This book is about understanding the principles of enzyme kinetics and knowing how to use mathematical models to describe the catalytic function of an enzyme. Coverage of the material is by no means exhaustive. There exist many books on enzyme kinetics that offer thorough, in-depth treatises of the subject. This book stresses understanding and practicality, and is not meant to replace, but rather to complement, authoritative treatises on the subject such as Segel's Enzyme Kinetics.
