Biochemistry and Biophysics is a growing enterprise worldwide, driven primarily by the widespread realization of the major contribution that can be made to biological science by a combination of truly state-of-the-art physical measurements with modern molecular biology. The field occupies a unique and central position at the intersection of biological, chemical, physical, and medical sciences. Most of the human biological functions and healthcare practices has basis of principles of biochemistry and biophysics. Therefore, nurses involved in providing nursing care must understand the biochemical and biophysical principles and their applications in healthcare practices. So that, nurses can assess, plan, implement and evaluate each care intervention more effectively and scientifically. This textbook is a modest attempt to present the basic principles and practices of biochemistry and biophysics in simple, lucid and illustrative manner by incorporating their applications to healthcare and nursing practices. The content of textbook is divided into two sections: Section–A Biochemistry and Section–B Biophysics. Section- A includes basics of biochemistry, cell, water, electrolytes, enzymes, digestions and absorption of food. Furthermore, biochemical aspects and metabolism of carbohydrates, protein and fat has been presented. Section–B includes basic physical principles and healthcare/ nursing applications of biophysics like motions, gravity, force, energy, work, heat, light, pressure, sound, electricity, electromagnetism, atomic energy and electronics. The content of biophysics has been presented using non-mathematical approach by incorporating adequate examples from healthcare and nursing sciences. In addition, it has been ensured that each physical principle is simply defined and discussed with its application to nursing practices. Content of this textbook will fully meet the needs of the nursing students studying in Post Basic BSc Nursing program, since it is designed according to the revised syllabus and guidelines given by Indian Nursing Council, New Delhi. In addition to this book will also serve the purpose of preparation of nurses for various competitive exams and job opportunities.
