(R) Taurine, an aminosulfonic acid, is neither, although it contains both an amino group and an acidic group. (C) beta-alanine, an isomer of alanine, is a non-proteogenic amino acid. (L) Alanine is one of the 20 proteogenic amino acids All 20 differ by the substituent on the alpha-carbon. So, in reality, calling taurine an amino acid is actually two errors in one small molecule.įigure 2. But even if you could magically convert taurine (Figure 2, Left) into its carbon analog beta-alanine (Center), it still would not technically be an amino acid in the strictest sense of the word because that term is typically reserved for proteogenic amino acids beta-alanine isn't one. Taurine doesn't fit the generic structure because it is an aminosulfonic acid, where sulfur (in the sulfonic acid oxidation state) replaces carbon. (Right) Two non-proteogenic (but biologically important) amino acids. The yellow arrows indicate the alpha-carbon (same location as R in the figure on the left). (Center) Two of the 20 proteogenic (used to make proteins) amino acids. They differ only by the pink "R" groups - 20 of them. (Left) The generic structure for all 20 amino acids that form proteins. But if you're chemically liberal you can expand this definition by including any molecule, naturally occurring or not, that contains both an amino group and a carboxylic acid, (Figure 1, Right).įigure 1.
Why is this wrong? For starters, the term "amino acid" is typically used to denote one of the 20 building blocks of proteins (Figure 1, Left, Center).
The Internet gets this wrong right and left.
