Biochemistry is the most fast growing subject, extensively applicable to understand the disease at molecular level. Estimations of various biochemical parameters definitely give an insight to understand the normal metabolism and its aberrations leading to diseases, which forms the foundation for medicine.

Biochemistry should be encouraged in relation to health and disease which will make the subject more interesting and fascinating to the students. We are hopeful that this practical biochemistry book will help the medical students to envisage about the various facts encountered in the reactions in the body.

Dear students let us admit that ‘Biochemistry’ is rarely a medical graduates' favorite given the fact that it is non- ‘Clinical’, extensive, volatile and there is little in it to arouse any amount of interest in the medical graduates. In our teaching biochemistry to undergraduate medical students we have realized practicals is where they have shown some amount of enthusiasm towards biochemistry.6

Our main aim is to make this book simple and attractive to the undergraduate medical students as far as possible which is apparent from the title of the book. Towards achieving this goal, each practical session has been reorganized such that it becomes easy to understand. Wherever possible, the subject is presented in tabular format such that it becomes very concise; and all test results are given in color such that the simple task of reading the book itself realizes one doing the practicals. Fundamental concepts and principles behind each experiment are explained in a simple way.

Our only genuine concern is to help you to understand the subject in an easy and organized way such that this little knowledge comes as a big help not only in your exams but also in your future medical career.

We will be glad to accept constructive criticism and fruitful suggestion to make this book a better one.

It is our proud privilege to express our gratitude to our colleagues Dr Govindaswamy, Dr I C Vinay, Dr Jyothi R S and Mr Anil Kumar Suryavamshi involved in reviewing the manuscript of this book.

I take this opportunity to thank computer operators Mrs Veena Jayaram and Mr Sunder for their help in preparing the manuscript. We are also very grateful to our lab technicians Mr Vasant, Mr Shankar, Mr Girish and Miss Rajeshwari for their valuable assistance.
