Once hydrogen bonds form between every fourth amino acid in a polypeptide chain, the chain begins to twist into the secondary structure known as a(n) alpha helix.
Amino acids are organic compound. Amino acids contains amine and carboxyl functional group. Amino acids is the building block of life these are the molecules that combine to form proteins.
A unique sequence of amino acids joined by peptide bonds is called polypeptide.
Thus from the above conclusion we can say that Once hydrogen bonds form between every fourth amino acid in a polypeptide chain, the chain begins to twist into the secondary structure known as a(n) alpha helix.
