Classification of Amino Acids
The 20 standard amino acids are the alphabet of every protein in your body — from haemoglobin to histones, collagen to antibodies. Understanding how they are classified by their side chains is not an act of memorisation; it is the key to predicting how proteins fold, how enzymes work, and why certain mutations cause disease. […]

Water, Electrolytes & Biological Solvents
Water is not just a passive backdrop for biochemistry — it is an active participant in virtually every reaction that keeps you alive. Understanding how water behaves as a solvent, how electrolytes distribute across compartments, how pH is defended, and how membranes control ionic traffic gives you the mechanistic foundation to reason through acid-base disorders, […]

pH, Buffers & Acid-Base Chemistry — The Henderson-Hasselbalch Equation Explained
Acid-base chemistry is the silent infrastructure running beneath every biochemistry topic you will ever study — enzyme kinetics, amino acid behaviour, oxygen delivery, and drug pharmacology all depend on understanding how protons move and how biological systems resist those movements. Master the Henderson-Hasselbalch equation and physiological buffering once, and you gain a tool that explains […]

The Central Dogma of Molecular Biology — High-Yield Guide
Every protein your body has ever made — from haemoglobin carrying oxygen in your red cells to the enzyme catalysing the reaction you are studying right now — followed the same three-step production line. DNA stores the blueprint, transcription copies it into RNA, and translation reads that copy to build a protein. This flow of […]

What Is Biochemistry? A Medical Student’s Guide
Biochemistry is the molecular language of life — it explains why a single enzyme defect can kill a newborn, how a statin lowers your patient’s cholesterol, and why fasting shifts your body from glucose to ketone metabolism. Before you can master any of those pathways, you need a clear map of what biochemistry is and […]
