What is the tertiary structure of a protein?

0:19

The tertiary structure is the overall three-dimensional shape of a single polypeptide, determined by interactions between the R groups of distant amino acids. These interactions include hydrogen bonds, ionic bonds, hydrophobic interactions, and disulfide bridges. Tertiary structure is what gives a protein its functional shape.
