Structure is achieved when a protein folds into a compact, three-dimensional between side-chain r groups of amino acids. structure is the sequence of amino acids in a protein. structure describes the alpha helices and beta-sheets that are formed by hydrogen bonding between backbone atoms located near each other in the polypeptide chain. structure is the result of two or more protein subunits assembling to form a larger, biologically active protein complex. a. primary,
b. secondary,
c. tertiary,
d. quaternary
