📘 About the Authors
Together, they present a textbook that balances scientific depth with readability — making it ideal for self-study and academic use alike.
🔬 Core Focus Areas in the Book
The book is organized into six major parts, each targeting critical aspects of biochemistry:
1. Biomolecules: Structure and Functions
The book begins with an in-depth study of biological macromolecules:
- Carbohydrates – Monosaccharides, disaccharides, polysaccharides, and their biological roles.
- Lipids – Fatty acids, triglycerides, phospholipids, steroids, and their metabolic functions.
- Proteins – Structure levels (primary to quaternary), types, and functions.
- Nucleic Acids – DNA, RNA, and their biochemical significance.
This section builds the biochemical foundation needed for further study.
2. Enzymes and Coenzymes
This part explains:
- Enzyme kinetics and mechanisms of action
- Factors affecting enzyme activity
- Coenzymes like NAD⁺, FAD, coenzyme A
- Enzyme inhibition (competitive and non-competitive)
Real-life clinical correlations, such as enzyme deficiencies and diagnostic enzymes, are also discussed.
3. Metabolism and Bioenergetics
Arguably the most detailed section, it covers:
- Carbohydrate metabolism: Glycolysis, gluconeogenesis, glycogenolysis, TCA cycle
- Lipid metabolism: Beta-oxidation, fatty acid synthesis, ketogenesis
- Protein and amino acid metabolism
- Nucleotide metabolism
- Energy production (ATP synthesis)
The Krebs cycle, electron transport chain, and oxidative phosphorylation are clearly explained, linking metabolism to energy.
4. Clinical and Applied Biochemistry
One of the most appreciated features of the book is its clinical relevance. This section explains how biochemical processes are altered in disease states:
- Diabetes mellitus
- Liver function and jaundice
- Renal failure
- Cancer metabolism
- Acid-base balance disorders
The inclusion of diagnostic tests, biochemical markers, and case-based examples makes this section valuable for medical students.
5. Molecular Biology and Biotechnology
Modern advancements are covered extensively here:
- DNA replication, transcription, translation
- Genetic code and mutations
- Recombinant DNA technology
- PCR (Polymerase Chain Reaction)
- Gene therapy and CRISPR
These topics are presented in a simplified manner with clear diagrams, making complex ideas accessible.
6. Recent Advances and Special Topics
This part includes up-to-date information on:
- Human genome project
- HIV/AIDS biochemistry
- Oxidative stress and antioxidants
- Molecular basis of cancer
- Personalized medicine
Such topics are essential for keeping pace with today’s biomedical research and clinical practices.
🎯 Target Audience
This book is primarily intended for:
- MBBS, BDS, and BSc Nursing students
