Biochemistry 4th Edition written by U. Satyanarayana & U. Chakrapani is a great book for Biochemistry studies, Book available for PDF download. Biochemistry by Satyanarayana book ‘Biochemistry’ has undoubtedly become one of the most preferred textbooks (in India and many other countries) by the students as well as teachers in medical, biological and other allied sciences. It is certainly a book of choice and a true companion to all learning biochemistry, hence appropriately regarded by many as the ‘Bible of Biochemistry’. Biochemistry by Satyanarayana book has undergone three editions, several reprints, and revised reprints in a span of 13 years. The advances in biochemistry are evergrowing due to the exponential growth of the subject. Further, the critical comments, frank opinions and constructive suggestions by teachers and students need to be seriously considered. All Biochemistry by Satyanarayana necessitates frequent revision of the book.

In this biochemistry book, biochemistry subject is perhaps the most fascinating it deals with the chemical language of life, be it animal, human, plant or microorganism. No other science subject has as much application as biochemistry to the disciplines of health, veterinary, Medicine, Agriculture Technology & bioengineering. This necessitates a totally different outlook for the books on biochemistry subjects. There are many biochemistry textbooks on the market. Some of them are purely basic while others are applied, and there are very few books that cover both these aspects together.

Biochemistry by Satyanarayana book, ‘Biochemistry’ is unique with a simultaneous and equal emphasis on basic and applied aspects of biochemistry. Biochemistry by Satyanarayana textbook primarily is an integration of Medical Science and pure sciences, comprehensively written to meet the curriculum requirements of undergraduate courses in medical, Dental, pharmacy, life-sciences and other categories (agriculture, veterinary, etc.) where students learn biochemistry as one of the subjects. The tendency among the particularly medical students is to regard biochemistry as being mostly concerned with complicated & unimportant metabolic (chemical) pathways. Biochemistry by Satyanarayana book gives a new orientation to the subject of biochemistry so that the students appreciate the great importance and significance of the application of biochemistry to medicine.

Biochemistry by Satyanarayana book is designed to develop in students a sustained interest and enthusiasm to learn and develop the concepts in biochemistry in a logical and stepwise manner. It incorporates a variety of pedagogic aids, besides color illustrations to help the students understand the subject quickly and to the maximum. The summary and biomedical/clinical concepts are intended for rapid absorption and assimilation of the facts and concepts in biochemistry.

It will not be out of place to mention here how-and when-the book was born. The entire book was written in the early morning hours (between 2 AM-6 AM; when the world around is fast asleep), during which period I carry out my intellectual activities. After a sound sleep, a fresh mind packed with creative ideas and innovative thoughts has largely helped me to write Biochemistry by Satyanarayana book. My wife pleaded with me that I should not write topics like diabetes, Cancer, AIDS at home. In deference to her sentiment, I made a serious attempt to write those topics during my leisure time in the Department. But when I went through them in my serene mood of the early morning hours, I had to discard them in disappointment and rewrite them. Truly, each page of Biochemistry by Satyanarayana book was conceived in darkness and born at daybreak!

Biochemistry by Satyanarayana textbook is a distillation of my knowledge and teaching experience in biochemistry, acquired during the past 25 years. It contains predigested information on biochemistry for good understanding, assimilation, and reproducibility. Each page is crafted with a fine eye. The ultimate purpose of Biochemistry by Satyanarayana's book is to equip the reader with comprehensive knowledge in biochemistry with reference to basic as well as applied aspects. Although I have made every effort to make the book error-free, I am under no illusion. I welcome comments, criticism and suggestions from the faculty, students and other readers, and this will help me make improvements in the next edition.
