Polymer

The amino acids above form a molecule named Polypeptide, which is the polymer.

Examples

Protein is everywhere, believe it or not! The enzyme pepsin in the stomach that helps break down food is a protein. Also, the hormone insulin that sends out messages to the body is also a protein. Another protein is Hemoglobin, which helps blood carry oxygen.
