alpha-Helix is a secondary structure of proteins formed by twisting of – InterviewSolution

1.	alpha-Helix is a secondary structure of proteins formed by twisting of polypeptide chain into right handed screw like structures. Which type of interactions are responsible for making the alpha- helix structure stabel ?
Answer» Solution :The `alpha`-helix STRUCTURE of polypeptide chain is stabilized by intramolecular H-bonding in which `gt C=O` of one AMINO acid residue in one TURN FORMS a H-bond with `-NH-` group of the fourth amino acid in the adjacent turn.
