Answer :
The protein secondary structure shown in the figure represent α-helix.
The helical structures:
- The α-helix is the most prevalent kind of secondary structure in proteins.
- The first person to foresee the presence of α-helices was Linus Pauling.
- The first protein to have a three-dimensional structure was myoglobin, which was discovered by Max Perutz and John Kendrew using X-ray crystallography.
- The illustration below shows an instance of a α-helix. "Stick representation" is the name given to this style of protein structural depiction.
- There are other helical structures in proteins besides the α-helix.
- The 3 10α helix, which is supported by hydrogen bonds of the type I i+3), the α-helix, which is supported by hydrogen bonds of the type I i+5), and the left-handed L-α helix are further helical configurations.
- The 3 10 αhelix has a radius that is smaller than the α-helix, whereas the -helix has a radius that is bigger.
