Notes: L-Proline-d3 is intended for use as an internal standard for the quantification of L-proline (Item No. 30772) by GC- or LC-MS. L-Proline is a nonessential amino acid.{54262} It contains a pyrrolidine ring, which contains the α-amino nitrogen, and is highly rigid, properties that affect protein conformation and folding and can cause kinks and turns in protein secondary structure.{54262,54263} It is a substrate for the proton-coupled amino acid transporter 1 (PAT1) and an inhibitor of acetylcholinesterase (AChE; Ki = 86 µM).{54264,54265} L-Proline accumulates in plants under environmental stress and is important for environmental stress tolerance through its involvement in protein synthesis, redox balance maintenance, osmoprotection, and signaling.{54266}
