β-alanine

β-Alanine (3-Aminopropanoic acid) is a naturally occurring beta amino acid formed in vivo by the degradation of dihydrouracil and carnosine. It acts as a neurotransmitter by activating glycine and GABA receptors.

β-cyano-L-Alanine (Beta-cyano-l-alanine) is a commonly occurring nitrile found in higher plants.

β-N-Methylamino-L-alanine hydrochloride (L-BMAA hydrochloride) is a neurotoxin produced by cyanobacteria that may contribute to the development of amyotrophic lateral sclerosis (ALS) and possibly other neurodegenerative diseases.

Anserine (L-Anserine) is a dipeptide containing β-alanine and histidine, which can be found in the skeletal muscle and brain of mammals and birds. Anserine is not cleaved by serum carnosinase and act as biochemical buffers, chelators, antioxidants, and anti-glycation agents. Anserine improves memory functions in Alzheimer's disease (AD)-model mice.

Ac-Ala-OH (N-Acetyl-L-alanine) is a substrate for Guanine nucleotide-binding protein G(I) G(S) G(O) gamma-2 subunit, Myelin basic protein, GTP-binding nuclear protein Ran, Tropomyosin alpha 4 chain, HIV-1 Rev binding protein 2, Xaa-Pro dipeptidase, Thymosin beta-10, Actin-like protein 3, Alanine aminotransferase, Serine threonine protein Phosphatase PP1-beta catalytic subunit,10 kDa heat shock protein (mitochondrial), Calmodulin and Beta-1-syntrophin.

Methyl 3-aminopropanoate hydrochloride (β-Alanine methyl ester hydrochloride) is the ethyl ester of the non-essential amino acid β-alanine.

3-Amino-2-methylpropanoic acid (α-Methyl-β-alanine) is the product from the conversion of N-carbamyl-beta-aminoisobutyric acid by the enzyme Beta-ureidopropionase (EC 3.5.1.6), the last step in pyrimidine degradation. Beta-ureidopropionase deficiency is an inborn error of pyrimidine degradation associated with neurological abnormalities.

Arecaidine hydrochloride may have carcinogenesis.

Ureidopropionic acid (3-Ureidopropionic acid) is an intermediate in uracil metabolism, produced from dihydrouracil by the enzyme dihydropyrimidase and further decomposed to beta-alanine by beta-ureidopropionase. It is a urea derivative of beta-alanine. High levels of Ureidopropionic acid are found in individuals with beta-ureidopropionase (UP) deficiency. Enzyme deficiencies in pyrimidine metabolism are associated with severe toxicity to the antineoplastic agent 5-fluorouracil.
