Augustin-Pierre Dubrunfaut Explained

Augustin-Pierre Dubrunfaut (in French pronounced as /ogystɛ̃ pjɛʁ dybʁœ̃fo/; Lille, 1 September 1797 – Paris, 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]
