The specific sequence of amino acids joined by peptide bonds to form a polypeptide
1 of 7
Secondary Structure
The backbone of the protein and the conformational shape it takes when the non-R groups of the amino acid react and bond with one another
2 of 7
Alpha Helix
These bonds make the alpha helix a strong and stable structure that acts as a solid, rod-like cylinder, providing mechanical support to the protein.
3 of 7
Beta Pleated Sheet
Formed when the carboxyl and amine groups of the polypeptide backbone form hydrogen bonds with one another
4 of 7
Tertiary Structure
The 3D structure that a protein takes when the secondary structures of polypeptides interact and fold in on themselves. This structure is held together by numerous bond types.
5 of 7
Quaternary Structure
The most complex conformation a protein can take. Not all proteins have this level of structure, however, when two or more polypeptide chains come into close contact, they bond together to form a quaternary protein structure.

Polypeptides
Amino acids can join together to form larger molecules called polypeptides. Polypeptides are long chains of amino acids covalently linked to one another by peptide bonds.
