The document discusses the concept of protein tertiary structure, defined as the geometric shape of a protein formed by a single polypeptide chain and various protein secondary structures. It highlights the importance of interactions among amino acid side chains, which include disulfide bonds, hydrophobic interactions, hydrogen bonds, and ionic interactions. References for further information on the topic are provided, including links to educational resources and notable literature.

The term protein tertiary structure refers to
a protein's geometric shape.
The tertiary structure will have a single
polypeptide chain "backbone" with one or
more protein secondary structures, the protein
domains.
Amino acid side chains may interact and bond in
a number of ways.
The interactions and bonds of side chains within a
particular protein determine its tertiary structure.
