D) those with ionized R-groups.
E) two Cys.

Question

Quizplus · Accepted Answer

The middle region of the F1F1F1S1F1F1F10 turn is known for its tight turn and restricted conformational space. Proline and glycine residues are well known for their ability to form tight turns due to their unique conformational properties. Additionally, the lack of bulky R-groups allows for more flexibility in the peptide backbone, further contributing to the tight turn formation. Therefore, choice C, Pro and Gly, is the best answer.
