Rapid advances in the area of molecular biology have been incorporated. Specific Learning Objectives provided at the beginning of each chapter to specify what student should learn from that chapter. NEW: Color coding used to represent enzyme names instead of numbers for better readability. NEW: Major pathways have been collated at a single place to make it more reader friendly. NEW: Important classifications, facts, tables, cyclic reactions, etc. have been depicted as Key Concepts at the end of chapters for quick revision.

A major attraction of this edition is the incorporation of Clinical Case Studies in almost all the chapters to help students identify the clinical relevance of biochemistry. For integrated learning and early clinical exposure (which is a major highlight of the new curriculum), clinical chemistry and applied aspects are incorporated in Boxes, which are “nice to know” for students.
