So, I’m suppose to look up two “newsworthy” organic molecules. I found one molecule that, while not newsworthy, was totally interesting. In our Interesting Fact, ethylenediaminetetraacetic acid (EDTA) is a molecule that turns metals into complexes to prevent them from further reacting with other substances (like metals that are used as co-factors for enzymes). When ingested, it also helps iron absorption in human beings. Apparently when treating food with it, it also prevents a “metallic taste” from developing in foods. Those foods include various canned foods and McDonald’s Big Mac sauce. So if your Big Mac does taste a bit like metal and makes you look a bit like this 
, it’s probably because they didn’t add enough of this. You can take a more in depth look at it at http://www.chm.bris.ac.uk/motm/edta/edtah.htm.
