L-Alanine (symbol Ala or A) 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.
L-Alanine is widely used as nutrition supplements, as sweetener and flavor enhancer in the food industry, as flavor enhancer and preservative in the beverage industry, as intermediate for medicine manufacturing in pharmaceutical, as nutritional supplement and sour corrective agent in agriculture/animal feed, and as intermediate in manufacturing of various organic chemicals.
L-Alanine is an amino acid that can act as a skin-conditioning agent. It is usually used in combination with other amino acids.
