The ____of a protein largely determines its secondary and tertiary structures.
The polypeptides of a protein largely determine its secondary and tertiary structures. In secondary and tertiary structures the polypeptide chain forms either an alpha helix or a beta sheet. Sheets are stabilized by hydrogen bonds.
Secondary and tertiary structures are made of long polypeptide chain. Within the long protein chains there are regions in which the chains are organized into regular structures known as alpha-helices and beta-pleated sheets. These are the structures in proteins, which determine what kind of protein is it. These secondary and tertiary structures are held together by hydrogen bonds.
