Substance Name: beta-Alanine
RN: 107-95-9
UNII: 11P2JDE17B
InChIKey: UCMIRNVEIXFBKS-UHFFFAOYSA-N
Note
- An amino acid formed in vivo by the degradation of dihydrouracil and carnosine. Since neuronal uptake and neuronal receptor sensitivity to beta-alanine have been demonstrated, the compound may be a false transmitter replacing GAMMA-AMINOBUTYRIC ACID. A rare genetic disorder, hyper-beta-alaninemia, has been reported.
