Vedclass · Answer

(B) In the secondary structure of proteins,the polypeptide chain is folded into specific shapes due to hydrogen bonding between the amino acid residues.Specifically,the $\alpha$-helix is a common secondary structure where the polypeptide chain is coiled into a rigid,tubular,or spiral shape,stabilized by intramolecular hydrogen bonds between the carbonyl oxygen of one amino acid and the amino hydrogen of another residue located four positions away.Therefore,the correct term for this structure is the helix.
