Example structure of macromolecules

Here are examples of the structures of the four main types of macromolecules:

Carbohydrates: A simple sugar like glucose has a ring structure.
C₆H₁₂O₆

Lipids: A triglyceride is formed from one glycerol molecule and three fatty acid chains.
Glycerol + 3 Fatty Acids → Triglyceride + 3 H₂O

Proteins: A polypeptide chain is a linear sequence of amino acids linked by peptide bonds. The specific sequence determines the protein's final 3D shape.

Nucleic Acids: DNA typically forms a double helix, where two strands of nucleotides wind around each other. Each strand is a sequence of nucleotides.
