D-Proline Chemical Properties,Uses,Production

Chemical Properties

White to off-white powder

Occurrence

D-proline is an isomer of the naturally occurring amino acid, L-Proline. D-amino acids have been found in relatively high abundance in human plasma and saliva. These amino acids may be of bacterial origin, but there is also evidence that they are endogenously produced through amino acid racemase activity.

Uses

proline is a skin-conditioning agent. An amino acid found in the collagen molecule.

Uses

Used in the synthesis of (R)-(+)-N-Boc-Pipecolic Acid, (S)-(-)-Coniine, (S)-(+)-Pelletierine, (+)-.beta.-Conhydrine, and (S)-(-)-Ropivacaine and formal synthesis of (-)-Lasubine II and (+)-Cermizine C.

Uses

Labelled D-Proline Lasubine II and (+)-Cermizine C.

Definition

ChEBI: D-proline is the D-enantiomer of proline. It has a role as a mouse metabolite. It is a D-alpha-amino acid and a proline. It is a conjugate base of a D-prolinium. It is a conjugate acid of a D-prolinate. It is an enantiomer of a L-proline. It is a tautomer of a D-proline zwitterion.
