Augustin-Pierre Dubrunfaut

Augustin-Pierre Dubrunfaut (French pronunciation: ​[ogystɛ̃ pjɛʁ dybʁœ̃fo]; 1 September 1797, Lille – 7 October 1881[1]) 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.[2][3][4][5] 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.[6] He also discovered maltose, although this discovery was not widely accepted until it was confirmed in 1872 by Cornelius O'Sullivan.[7]
