Biochemistry is a vast field of study. It is primarily concerned with all the varied chemical processes related to living organisms. The in-depth study of biomolecules like proteins, carbohydrates, lipids, etc. is a major focus of this field. The understanding of these biomolecules facilitates the study of tissues, organs as well as the processes occurring within living cells. Biochemistry also delves into the processes of metabolism. It is the mechanism by which energy is harnessed by the cells via chemical reactions. This textbook provides comprehensive insights into the diverse areas of biochemistry. Different approaches, evaluations and methodologies have also been included herein. As this field is emerging at a rapid pace, the concepts of this book will help the readers understand the fundamental concepts and applications of this subject.
