On: Aspartame and cancer – new evidence for causation

> Aspartame is an amino acid right?

No, that's not right. It's a peptide (a unit composed of amino acids), not an amino acid.

> Isn’t it going to be in all sorts of proteins then?

Proteins are made of peptides but not all peptides are common in proteins, no.

> Doesn’t that make it rather implausible that it is toxic?

No, lots of proteins are toxic to particular organisms, too.

The amino acid in question is apparently https://en.wikipedia.org/wiki/Aspartic_acid, a chemical component of aspartame, and the origin of the latter's name, but not at all the same substance.
