Beschreibung

Allgemeine Beschreibung

β-Alanine is a rate-limiting precursor of carnosine, a cytoplasmic dipeptide which is present in human skeletal muscles in high concentrations.

Anwendung

β-Alanine may be used as a reference standard for the determination of β-alanine in:

• Potato tubers by gas chromatography-mass spectrometry (GC-MS).
• Human plasma, urine, and cerebrospinal fluid samples by liquid chromatography-tandem mass spectrometry (LC-MS/MS).
• Striatal microdialysis samples by high performance liquid chromatography-fluorescence detection (HPLC-FLD) with ortho-phthalaldehyde-mercaptoethanol derivatization.
• Fermented soybean paste, Cheonggukjang, by GC-MS operating in selected-ion monitoring (SIM) mode and principal component analysis (PCA).

Biochem./physiol. Wirkung

Diese endogene β-Aminosäure ist ein unselektiver Agonist von Glycin-Rezeptoren und ein Ligand des G-Protein-gekoppelten Orphan Rezeptors TGR7 (MrgD). Der β-Alaninfluss spielt eine zellschützende Rolle indem er die osmotische Stabilität von Meeresorganismen, preimplantation-Mausembryos und Säugerzellen unter hypoxischem Stress stabilisiert.
