Regulation of Salicylic Acid and N-Hydroxy-Pipecolic Acid in Systemic Acquired Resistance [PDF]
In plants, salicylic acid (SA) is a central immune signal that is involved in both local and systemic acquired resistance (SAR). In addition to SA, several other chemical signals are also involved in SAR and these include N-hydroxy-pipecolic acid (NHP ...

An Artificial Pathway for N-Hydroxy-Pipecolic Acid Production From L-Lysine in Escherichia coli [PDF]
N-hydroxy-pipecolic acid (NHP) is a hydroxylated product of pipecolic acid and an important systemic acquired resistance signal molecule. However, the biosynthesis of NHP does not have a natural metabolic pathway in microorganisms.

Pipecolic Acid Quantification Using Gas Chromatography-coupled Mass Spectrometry [PDF]
Pipecolic acid (Pip), a non-proteinacious product of lysine catabolism, is an important regulator of immunity in plants and humans alike. For instance, Pip accumulation is associated with the genetic disorder Zellweger syndrome, chronic liver diseases ...

Intracerebroventricular Injection of L-Pipecolic Acid Exerts Hypnotic Effects Without Activating NMDA Receptors in Neonatal Chicks under Social Isolation-induced Stress [PDF]
L-Pipecolic acid is an intermediate of L-lysine catabolism. Its central injection exerted a hypnotic effect on the brain, which was partially mediated by the activation of γ-aminobutyric acid-A and γ-aminobutyric acid-B receptors. L-Proline has also been

In Vitro Fertilisation of Mouse Oocytes in L-Proline and L-Pipecolic Acid Improves Subsequent Development [PDF]
Exposure of oocytes to specific amino acids during in vitro fertilisation (IVF) improves preimplantation embryo development. Embryos fertilised in medium with proline and its homologue pipecolic acid showed increased blastocyst formation and inner cell ...
