L-Alanine

Alanine was one of the first amino acids to be synthesized before its isolation from natural sources. Adolph Strecker synthesized alanine from acetaldehyde via its condensation product with ammonia and hydrogen cyanide in 1850. The name alanine derives from the term aldehyde, reflecting one of the starting reagents. Alanine was discovered in natural sources (protein) in 1875.

Load 3D Structure of Alanine

L-Alanin is a nonessential amino acid that occurs in high levels in its free state in plasma. It is produced by reductive amination of pyruvate. It is involved in sugar and acid metabolism, increases immunity, and provides energy for muscle tissue, brain, and the central nervous system.
