β-Aminobutyric acid (BABA) is an isomer of the amino acid aminobutyric acid with the chemical formula C 4 H 9 NO 2.It has two isomers, α-aminobutyric acid and γ-aminobutyric acid (GABA), a neurotransmitter in animals that is also found in plants, where it may play a role in signalling.
Alanine (symbol Ala or A), [4] or α-alanine, is an α-amino acid that is used in the biosynthesis of proteins. It contains an amine group and a carboxylic acid group, both attached to the central carbon atom which also carries a methyl group side chain. Consequently it is classified as a nonpolar, aliphatic α-amino acid.
An amino acid contains both acidic (carboxylic acid fragment) and basic (amine fragment) centres. The isomer on the right is a zwitterion. Tautomerism of amino acids follows this stoichiometry: RCH(NH 2)CO 2 H ⇌ RCH(N + H 3)CO − 2. The ratio of the concentrations of the two species in solution is independent of pH.
Amino acids with the structure NH + 3 −CXY−CXY−CO − 2, such as β-alanine, a component of carnosine and a few other peptides, are β-amino acids. Ones with the structure NH + 3 −CXY−CXY−CXY−CO − 2 are γ-amino acids, and so on, where X and Y are two substituents (one of which is normally H). [7]
α-Aminobutyric acid (AABA), also known as homoalanine in biochemistry, is a non-proteinogenic alpha amino acid with chemical formula C 4 H 9 NO 2. The straight two carbon side chain is one carbon longer than alanine, hence the prefix homo-. Homoalanine is biosynthesised by transaminating oxobutyrate, a metabolite in isoleucine biosynthesis.
Aminobutyric acid or aminobutanoic acid may refer to any of three isomeric chemical compounds: α-Aminobutyric acid (AABA) β-Aminobutyric acid (BABA)

β-alanine, an example of a β-amino acid. The amino group attaches not to the α carbon but to the β-carbon, which in this case is a methylene group.. Beta-peptides (β-peptides) are peptides derived from β-amino acids, in which the amino group is attached to the β-carbon (i.e. the carbon two atoms away from the carboxylate group).
