Beta-Amino Acids

Beta-amino acids are analogs of alpha-amino acids where the amino group is attached to the beta-carbon instead of the alpha-carbon. The most common and well known beta-amino acid is beta-alanine, as known as 3-aminopropionic acid.

The D and L nomeclature has not been applied consistently to beta-amino acids. To avoid confusion, AAPPTec uses R and S nomeclature with beta-amino acids.

(R)-beta-Phe (S)-beta-Phe



Note that (R)-beta-Phe has the same relative configuration of the asymmetric carbon as L-Phg. Please carefully check which stereoisomer you need before ordering.

(R)-beta-Phe L-Phg
