Description

White to off-white powder

Solid

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.|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.
