The primary structure of proteins is the . The primary structure contains the information necessary for the formation of secondary structure, including the and the . Secondary structure of proteins is stabilized by the formation of bonds.

A. amino acid sequence; β pleated sheet; α helix; disulfide
B. α helix; amino acid sequence; β pleated sheet; hydrophobic
C. amino acid sequence; α helix; β pleated sheet; hydrogen
D. amino acid sequence; α helix; β pleated sheet; peptide
E. β pleated sheet; α helix; amino acid sequence; hydrogen

option C

Explanation: The primary structure of protein is determined basically by the linear chain of amino acid sequences containing the information which is necessary for the formation of the secondary structure which can be divided into 2; the helix and beta pleated sheets. This secondary structures are then further stabilized enjoying protein stability by the formation of hydrogen bonds. For example in the alpha helix, Hydrogen bonds exists between every fourth C double bond O to further stabilize its secondary structure
