Description

The three-dimensional shape of a protein determines its function. The shape of proteins can change by small or large amounts; another term for shape is conformation.

Molecular Conformations introduces the fundamental physical and biochemical concepts that determine the conformation of a protein. The book starts by describing how DNA is converted into proteins and then continues with those factors that influence conformational change in a protein.

The book is essential reading for anyone who wants to understand how proteins execute their biochemical functions.
