Question

Understand alpha helices and beta pleated sheets Question The coiling of an a-helix is maintained in position by which of the following bonds? Select the correct answer below: O hydrogen bonds between the oxygen atom in the carbonyl group in one amino acid and the hydrogen atom of the hydroxyl group in an R-group of another amino acid that is four amino acids farther along the chain O hydrogen bonds between the oxygen atom in the carbonyl group in one amino acid and the hydrogen atom in the amine group of another amino acid that is four amino acids farther along the chain ionic interactions between the R-group of one amino acid and the R-group of another that is four amino acids farther along the chain O amide bonds between the carbon atom in the carbonyl group in one amino acid and the nitrogen atom in the amine group of another amino acid that is four amino acids farther along the chain P FEEDBACK MORE INSTRUCTION SUBMIT Content attribution

Answer 1

Coiling of an $\alpha$ -helix: option 2 is correct i.e.hydrogen bonds between the oxygen atom in the carbonyl group in one amino acid and the hydrogen atom in the amine group of another amino acid that is four acids farther along the chain. Below the structure given showing bonding pattern in $\alpha$ -helix :
