Proteinogenic
From Academic Kids
Proteinogenic amino acids are those 20 amino acids that are found in proteins and that are coded for in the standard genetic code. Proteinogenic literally means protein building.
Non-proteinogenic amino acids are either not found in proteins (like carnitine, GABA, or L-DOPA), or not coded for in the standard genetic code (like hydroxyproline). The latter often result from posttranslational modification of proteins. Template:Biochem-stub
