Common NameL-Alpha-aminobutyric acid
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 exists in all eukaryotes, ranging from yeast to plants to humans. L-alpha-Aminobutyric acid is found, on average, in the highest concentration within milk (cow). L-alpha-Aminobutyric acid has also been detected, but not quantified in, several different foods, such as anatidaes (Anatidae), chickens (Gallus gallus), common peas (Pisum sativum), and domestic pigs (Sus scrofa domestica). This could make L-alpha-aminobutyric acid a potential biomarker for the consumption of these foods. L-alpha-Aminobutyric acid is a primary metabolite. Primary metabolites are metabolically or physiologically essential metabolites. They are directly involved in an organism’s growth, development or reproduction. Based on a literature review a significant number of articles have been published on L-alpha-Aminobutyric acid.
