Macromolecules Made Simple – Proteins, Carbs, Lipids & Nucleic Acids

If you're preparing for the DAT, macromolecules are one of those “must-know” categories that sneak into several biology questions—sometimes directly, sometimes as part of enzyme or genetic material topics.

Whether it's a diagram of DNA, a question about fatty acid structure, or identifying amino acid bonds, this blog will help you lock in everything you need to know with a clear visual breakdown and test-smart strategies.

📚 Key Macromolecule Comparison Table

Macromolecule	Monomer	Main Function	Example
Proteins	Amino acids	Structure, enzymes, transport	Hemoglobin, enzymes
Carbohydrates	Monosaccharides	Energy, structure	Glucose, cellulose
Lipids	Fatty acids + glycerol	Energy storage, insulation	Triglycerides, phospholipids
Nucleic Acids	Nucleotides	Store and transmit genetic info	DNA, RNA

🧠 Mnemonic: CLPN – “Cool Little Protein Nuggets”

🔍 What the DAT Likes to Test

1. Polymerization

   • Proteins = peptide bonds

   • Carbs = glycosidic linkages

   • Nucleic Acids = phosphodiester bonds

   • Lipids = ester bonds

2. Function Questions

   • “Which macromolecule forms enzymes?” → Proteins

   • “What stores genetic info?” → Nucleic Acids

3. Structure Identification

   • Recognizing ring vs. chain structures

   • Knowing that lipids are hydrophobic, proteins fold, and DNA is double-stranded

🧬 DAT-Style Strategy Tips

✅ Flashcard match practice: monomer ↔ polymer
✅ Group function memorization (e.g., energy vs. information storage)
✅ Drill polymer linkage types (DAT loves to ask these!)
✅ Use KOTC’s visuals and breakdowns for quick review + retention

🧠 Bonus: Visit kingofthecurve.org/studyscience to review animations and diagrams of each macromolecule in action.
