Question
The coiling in an ?-helix is stabilized by _____. repulsion of the R chains from each other, causing the coil to form with the R groups on the outside. disulfide bond formation between cysteines that are regularly spaced along peptide chains. the hydrophobic nature of the R chains, which causes the chain to coil with the R groups inward. the N–C–C repeat of the peptide backbone, allowing for regularly spaced peptide bonds between chain segments. hydrogen bonding of the N–H groups on one amino acid and the C=O groups on anothe The coiling in an ?-helix is stabilized by _____. repulsion of the R chains from each other, causing the coil to form with the R groups on the outside. disulfide bond formation between cysteines that are regularly spaced along peptide chains. the hydrophobic nature of the R chains, which causes the chain to coil with the R groups inward. the N–C–C repeat of the peptide backbone, allowing for regularly spaced peptide bonds between chain segments. hydrogen bonding of the N–H groups on one amino acid and the C=O groups on anotheExplanation / Answer
Answer: Hydrogen bonding of the N-H groups on one amino acid and the C=O groups on another.
Explanation:
The alpha helix (?-helix) is a common motif in the secondary structure of proteins and is a righthand-spiral conformation (i.e. helix) in which every backbone N?H group donates a hydrogen bond to the backbone C=O group of the amino acid located three or four residuesearlier along the protein sequence.
