Alanina molecola
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 infix -an- for ease of … See more Biosynthesis Alanine can be synthesized from pyruvate and branched chain amino acids such as valine See more Glucose–alanine cycle In mammals, alanine plays a key role in glucose–alanine cycle between tissues and liver.
