Highly Charged Protein Ions: The Strongest Organic Acids to Date

Highly Charged Protein Ions: The Strongest Organic Acids to Date
Fangtong Zhang, Toby T. Funston, Muhammad A. Zenaidee, Michael G. Leeming, William A. Donald
Highly charged protein ions are sufficiently acidic to protonate noble gases, such as argon (Ar) in ion–molecule reactions at ambient temperature. Such ions are the most acidic entities that have ever been isolated and detected. In their Communication (DOI: 10.1002/anie.201702781), W. A. Donald et al. report protein ion super acids that are formed using electrospray ionization supercharging which transfers proteins from solution (represented by fishes) to the gas phase (birds).
