In the IMAT (International Medical Admissions Test), the topic "The Chemistry of Living

Things" is part of the General Chemistry and Biology sections. Below is a breakdown of
topics, subtopics, and specific concepts/articles you should study for IMAT 2025 under The
Chemistry of Living Things.

🧪 Topic: The Chemistry of Living Things


This typically overlaps between Chemistry and Biology, especially Biochemistry.

📌 1. Biochemical Molecules (Macromolecules)

Subtopics:

 Carbohydrates
o Monosaccharides (glucose, fructose, galactose)
o Disaccharides (sucrose, lactose, maltose)
o Polysaccharides (starch, glycogen, cellulose)
o Glycosidic bonds
 Lipids
o Fatty acids (saturated vs unsaturated)
o Triglycerides
o Phospholipids
o Steroids (e.g., cholesterol)
o Functions (energy storage, insulation, cell membrane)
 Proteins
o Amino acids and peptide bonds
o Primary, secondary, tertiary, quaternary structures
o Enzymes (structure, function, specificity, denaturation)
 Nucleic Acids
o DNA and RNA structure
o Nucleotides (sugar, phosphate, nitrogenous bases)
o Base pairing rules (A-T, C-G for DNA; A-U for RNA)
o DNA replication, transcription, translation basics

📌 2. Water and Its Importance

Subtopics:

 Polarity of water
 Hydrogen bonding
 Cohesion and adhesion
 High specific heat
 Solvent properties
 Role in biological systems

📌 3. Enzymes and Metabolism

Subtopics:

 Role of enzymes as biological catalysts


 Substrate specificity
 Enzyme-substrate complex
 Active site, induced fit model
 Factors affecting enzyme activity (pH, temperature, concentration)
 Inhibitors: competitive vs non-competitive

📌 4. Energy and Biochemical Reactions

Subtopics:

 Endergonic vs exergonic reactions


 Activation energy
 Role of ATP
 Redox reactions in metabolism
 Cellular respiration (glycolysis, Krebs cycle, oxidative phosphorylation – basic overview)

📌 5. pH and Buffers

Subtopics:

 Acids and bases in biological systems


 pH scale
 Buffers and their role in maintaining homeostasis (e.g., bicarbonate buffer system in
blood)
📚 Recommended Articles/Concepts to Review:
Though the IMAT doesn't cite specific research papers, here are standard textbook sections and
concepts that align with the exam content:

 Campbell Biology (Chapters 2–5): Chemistry of life, water, carbon, macromolecules


 Biochemistry basics – Khan Academy or YouTube lectures
 A-level/IB Chemistry and Biology curriculum – especially biomolecules
 MIT OpenCourseWare – Intro to Biology/Organic Chemistry (for deeper review)

🧠 Tips for IMAT 2025 Preparation:


 Focus on functional groups in biomolecules (e.g., amino, carboxyl, hydroxyl).
 Understand structure-function relationships (e.g., how protein folding affects function).
 Be clear on enzymatic mechanisms and metabolic energy flow.
 Practice applying knowledge, not just memorizing (IMAT favors reasoning-based
MCQs).
