Introduction to Proteins : Structure, Function, and Motion, Second Edition

Description

"Introduction to Proteins shows how proteins can be analyzed in multiple ways. It refers to the roles of proteins and enzymes in diverse contexts and everyday applications, including medical disorders, drugs, toxins, chemical warfare, and animal behavior. This edition includes a brand-new chapter on enzymatic catalysis and biochemistry, an in-depth discussion of G-protein-coupled receptors (GPCRs), and a wider-scale description of methods for studying proteins."--Provided by publisher.
