Question

The unique cyclic structure of which of the following amino acids plays a central role in the formation of alpha helices and beta sheets?

- Lysine
- Arginine
- Valine
- Proline

Answer 1

Proline

Step-by-step explanation:

The unique cyclic structure of Proline plays a central role in the formation of alpha helices and beta sheets. Proline is different from other amino acids because its R group is linked to the amino group, forming a ring-like structure. This unique structure disrupts the regular structure of alpha helices and beta sheets, making Proline an important determinant in protein folding.
