Very large aggregates can be formed from protein subunits.For example, many thousands of actin molecules assemble into a microfilament.The primary structure of a protein refers to the sequence of amino acids in the polypeptide chain.

They should not be confused with random coil, an unfolded polypeptide chain lacking any fixed three-dimensional structure.
Several sequential secondary structures may form a "supersecondary unit".
Protein structures range in size from tens to several thousand amino acids.
By physical size, proteins are classified as nanoparticles, between 1–100 nm.
Tertiary structure refers to the three-dimensional structure of monomeric and multimeric protein molecules.
The α-helixes and β-pleated-sheets are folded into a compact globular structure.
Protein structure is the three-dimensional arrangement of atoms in an amino acid-chain molecule.
Proteins are polymers – specifically polypeptides – formed from sequences of amino acids, the monomers of the polymer.
It is strictly recommended to use the words "amino acid residues" when discussing proteins because when a peptide bond is formed, a water molecule is lost, and therefore proteins are made up of amino acid residues.
Post-translational modification such as phosphorylations and glycosylations are usually also considered a part of the primary structure, and cannot be read from the gene.
