Study Notes

Introduction to Large Biological Molecules

  • Large biological molecules, also known as macromolecules, are composed of thousands of covalently connected atoms.
  • Macromolecules are formed by joining small organic molecules together within cells.

Importance of Studying Macromolecules

  • Scientists study the structures of macromolecules because molecular structure and function are closely linked.

Polymers: A Type of Macromolecule

  • A polymer is a long molecule consisting of many similar building blocks called monomers.
  • Polymers are a type of macromolecule.
