DescriptionL-alpha-Aminobutyric acid, also known as (S)-2-aminobutanoic acid or (2S)-2-aminobutyrate, belongs to the class of organic compounds known as l-alpha-amino acids. These are alpha amino acids which have the L-configuration of the alpha-carbon atom. L-alpha-Aminobutyric acid is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. L-alpha-Aminobutyric acid exists in all eukaryotes, ranging from yeast to humans.
