About Augustin-Pierre Dubrunfaut
- Augustin-Pierre Dubrunfaut (French pronunciation: ?[ogyst?~ pj?? dyb?œ~fo]; 1 September 1797, Lille – 7 October 1881) was a French chemist. Mutarotation was discovered by Dubrunfaut in 1844, when he noticed that the specific rotation of aqueous sugar solution changes with time.
- In the same paper, he also identified that the inversion of sucrose in the presence of brewer's yeast (Saccharomyces cerevisiae) was not a consequence of fermentation.
- The organic fructose molecule was subsequently discovered by Dubrunfaut in 1847.
- He also discovered maltose, although this discovery was not widely accepted until it was confirmed in 1872 by Cornelius O'Sullivan.
