(r)pyrrolidine2carboxylic acid

(R)-pyrrolidine-2-carboxylic acid (D-Proline) is an isomer of the naturally occurring amino acid L-Proline. D-amino acids, including D-Proline, are found in relatively high abundance in human plasma and saliva, potentially originating from bacterial sources or endogenous production via amino acid racemase activity.

(S)-Pyrrolidine-2-carboxylic acid hydrochloride is a useful organic compound for research related to life sciences. The catalog number is T66349 and the CAS number is 7776-34-3.

L-Proline (proline) is a nonessential amino acid in humans. It is an essential component of collagen and is important for proper functioning of joints and tendons. It also helps maintain and strengthen heart muscles.

DL-Proline is a DL mixture of proline with multiple biological activities, capable of inhibiting EGFR and sodium-dependent proline transporters, and is commonly used in solid-phase or liquid-phase peptide synthesis.

L-Proline-15N is an isotopically labeled amino acid suitable for metabolic research, aiding in the exploration of amino acid metabolism pathways and mechanisms.
