marshall27 [118]

Secondary structure is created when a polypeptide chain folds as a result of a contact between the carbonyl group and the peptide linkage's N-H group. The given statement is True.

These proteins have the ability to fold themselves, thus their amino acid sequences must have all the necessary information. Peptide bonds are created when amino acids condense to form protein structures. The main structure of a protein is its arrangement of amino acids.

The dihedral angles of the peptide bonds determine the secondary structure, while the folding of protein chains in space determines the tertiary structure.

A peptide bond is a covalent connection that occurs when an amino acid's  α-amino group and carboxyl group are joined together without the need of water.
