Study Notes

Macromolecules Overview

Macromolecules are large molecules formed by polymerization, consisting of smaller units called monomers.
Naturally occurring macromolecules include:
- Polysaccharides: Examples include cellulose.
- Polypeptides: Include protein enzymes.
- Polynucleotides: DNA is a primary example.

Synthetic Macromolecules

Synthetic macromolecules are human-made and include polymers like:
- Nylon
- Polystyrene
These are created by linking and sometimes crosslinking monomers.

Definition and Importance of Polymers

The term "polymer" is derived from Greek, meaning "many parts."
Polymers have a high molecular weight compared to their constituent monomers.
Understanding polymers and their properties is crucial in various fields, including materials science and biology.
