This textbook from Academic Publishers is an English medium (अंग्रेजी माध्यम) book on Biochemistry, written by Debajyoti Das, prepared for First Professional MBBS students and also used by BDS, B.Sc. and M.Sc. students of biochemistry, life sciences, nursing and allied health science courses. This is the 14th Edition — a long-running title that has been revised across editions to keep pace with the syllabus. The book covers the subject comprehensively, beginning with the chemistry of biomolecules (जैव अणुओं का रसायन) and building through enzymes and bioenergetics into the metabolism of carbohydrates, lipids, proteins and nucleic acids, followed by molecular biology, hormones, nutrition and clinical biochemistry. Metabolic pathways are set out step by step with their regulation and the disorders that arise when a step fails, clinical correlations (क्लिनिकल सहसंबंध) connect the biochemistry to disease, and review questions (अभ्यास प्रश्न) at the end of the chapters support examination preparation. All content, terminology and explanations in this book are presented in the English language only.
