proline
Cyclic amino acid
Proline is one of the twenty amino acids that serve as building blocks for proteins in living organisms.
Unlike other amino acids, proline has a distinctive ring structure that creates kinks in protein chains, making it essential for collagen and other structural proteins.
Its rigid shape gives connective tissues like skin, tendons, and cartilage their characteristic strength and flexibility.
