Question

Stabilization of the unique coiled structure of an alpha helix in a protein is mostly attributed to

Answer 1

Answer:

Explanation:

Two major factors stabilize the alpha helix: intrachain H-bonding and minimization of steric interference between side chains. H-bonds (colored green here) form between the oxygen of one peptide bond and the amide hydrogen four amino acids away from it along the helix.

Answer 2

Answer:

Stabilization of the unique coiled structure of an alpha helix in a protein is mostly attributed to Hydrogen bond from the carbonyl oxygen of one amino acid to the amino group of second amino acid.

Explanation:

• An Alpha helix is a secondary structure that gives rhe description about the arrangement of main chain of a protein in space.
• The main chain is right-handed helix with side chain pointing away from helix axis.
• An alpha helix is rod like structure tightly coiled backbone.
• The alpha helix is stablized by bonding between the Hydrogen bond from the carbonyl oxygen of one amino acid to the amino group of second amino acid.
• The bond strength is very low of single hydrogen bond however multiple hydrogen bonding gives enough stablization to the protein structure.
• It is soluble in water,enzymes,antibodies, proteins etc.
• The function of alpha helix is to do Cell block construction.
