Webd-Alanine (d-Ala) is an unusual endogenous amino acid present in invertebrates and vertebrates. Compared to its l-isomer, the characterization of d-Ala is challenging because of the need for chiral resolution and the low amounts of the d-enantiomer present. With recent improvements in measurement capabilities, research on d-Ala, along with ... Alanine (symbol Ala or A), 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, its IUPAC systematic name is 2 … See more Alanine was first synthesized in 1850 when Adolph Strecker combined acetaldehyde and ammonia with hydrogen cyanide. The amino acid was named Alanin in German, in reference to aldehyde, with the See more Biosynthesis Alanine can be synthesized from pyruvate and branched chain amino acids such as valine, leucine, and isoleucine.
