Online Resources for Doing Organic Chemistry

Yes!!! 100% conversion to product, zero impurities, and a workup so easy I finished it while writing this sentence!Well, that’s what writing it down on an o-chem problem set might make it seem like at least. Turns out doing organic chemistry in practice isn’t so straightforward, but fortunately the work of generations of chemists have … Continue reading

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.
