comments: CHEBI keys in our DB refer to N-acetyl-L-cysteine https://www.ebi.ac.uk/chebi/CHEBI:28939. I think it's not 100% correct? According to this article https://pubmed.ncbi.nlm.nih.gov/31944156/#:~:text=Mercapturic%20acids%20(N%2Dacetyl%2D,%2Dconjugates%2C%20and%20mercapturic%20acids; --> there is not a single Mercapturic acid so I don't think we can link this to a key? Is this a sum parameter?
Mercaptuurzuur
