D-Proline is the D-stereoisomer of the amino acid proline.

Its chemical structure is defined by two key features:

1. Pyrrolidine Ring: Unlike other standard amino acids, proline has a secondary amine, where its amino group (-NH₂-) is fixed into a five-membered ring. This makes it an imino acid. This rigid ring structure heavily influences the conformation of protein chains, often causing kinks or bends.

2. D-Configuration: The "D" designation refers to the spatial arrangement of atoms around the chiral alpha carbon. In the L-form (the biological form), the carboxylate group is oriented in one specific way in a standardized projection. In the D-form, this spatial arrangement is the non-superimposable mirror image.

In summary, D-Proline is the non-natural, mirror-image form of proline, characterized by its unique, rigid pyrrolidine ring and its specific "right-handed" stereochemistry around the central carbon atom. It is primarily used in scientific research, for example, in the synthesis of peptides with specific structural properties or as a building block in organic chemistry and pharmaceutical research.
