5Preface to the Twelfth Edition
This book is revised keeping in view all categories of students and it addresses their needs in a simple and practical manner as biochemistry tries to explain the mystery of life in the language of chemistry.
I hope the book will be received warmly by the students as well as teachers for both desire maximum benefits out of it. All the chapters are revised to gain understanding and clarity. Suggestions to improve the future editions are most welcome and will be highly appreciated.
I would like to thank Shri Jitendar P Vij (Chairman and Managing Director) and Mr Tarun Duneja (Director Publishing) of M/s Jaypee Brothers Medical Publishers (P) Ltd, New Delhi for the publication of this book. Mr Subrata Adhikary (Author Coordinator) deserves special praise for this venture.

6Preface to the First Edition
Biochemistry currently occupies an eminent position particularly among medical subjects. However, there are few texts in the market at present which enable the students to acquire a working knowledge of the subject.
Having been connected with the teaching profession for the past few years, I am well acquainted with the difficulties encountered by the students while trying to master the subject.
The present book is the result of my humble attempt to overcome these handicaps and present the subject in a simple and easily comprehensible form.
Attempts have been made to illustrate the subject matter with diagrams and chemical formulae wherever necessary.
Special thanks to my publisher Shri Jitendar P Vij, without whose help, this book could not have seen the light of the day.
