1. Primary structure is the sequence of amino acids in a protein.
2.Quaternary structure is the result of two or more protein subunits assembling to form a larger . biologically active protein complex.
3. Tertiary structure is achieved when a protein folds into a compact , three dimensional shape stabilized by interactions between side-chain R groups of amino acids.
4. Secondary structure describes the alpha-helices and beta-sheets that are formed by the hydrogen bonding between backbone atoms located near each other in the polypeptide chain.
