I am happy to present the Text Book of Biochemistry for B.E. Biomedical Engineering students. Biochemistry is the language of living organisms. It is the most rapidly developing field in medicine. Biochemistry is gaining importance in the curricula of medicine, life science, nutrition and biomedical Engineering in universities and colleges. The book is designed to fulfill the needs of Undergraduate students of Biomedical Engineering, but it can be used by other students who require a good knowledge of biochemistry for their future carriers.
