Which of the following arrangements is usually not found in the secondary structure of proteins?
A) α-helix
B) double helix
C) random coil
D) pleated sheet
Secondary Structure
The level of protein structure involving hydrogen bonding between the backbone amide and carbonyl groups, forming alpha-helices and beta-pleated sheets.
Double Helix
The structure formed by double-stranded molecules of nucleic acids such as DNA.
Random Coil
A polymers' configuration in solution where it adopts an erratic, non-ordered shape due to the random distribution of the torsion angles along its chain.
- Explain the development and importance of alpha-helices and beta-sheets within the secondary structure of proteins.
