Questions are raised about “unclick” reaction

Click chemistry, a term used to describe a number of high yield reactions, is used far and wide by chemists. The azide alkyne Huisgen cycloaddition typifies click chemistry and awhile back, I described it as my favorite reaction.

Thanksgiving chemistry- cranberries and your blood

To do the biological study of how particular (good) chemicals like antioxidants affect people, there needs to be a quick, reliable, and consistent way to measure those chemicals in humans. Furthermore, a good method would test for multiple chemicals, because the health benefits from some chemicals only exist in the presence of others (phenolic acids and flavonoids in this case). The authors of this paper demonstrate a gas-chromatography mass-spectrometry (GC-MS) method to investigate how some of the chemicals present in cranberries (from cranberry juice) go into your bloodstream after you ingest them.
