a.
side chain groups like the hydroxyl of tyrosine
b. the hydrogen of the carbonyl oxygen, the amino nitrogen
c. the hydrogen of the amino nitrogen, the carbonyl oxygen
d. hydrophobic interactions between non - polar side chains like tryptophan

Accepted Answer

***C*** ∻Key Concept∻ ⚹Hydrogen Bonding in Alpha-Helices⚹ ∻Explanation∻ ⚹In an alpha-helix, hydrogen bonds form between the hydrogen of the amino nitrogen and the carbonyl oxygen of the peptide backbone. This stabilizes the helical structure.⚹◊What role do hydrogen bonds play in stabilizing the alpha-helical configuration of a polypeptide according to the information provided by the OCR model?⍭ Generate me a similar question◊
