Matches in DBpedia 2014 for { ?s ?p Barfoed's test is a chemical test used for detecting the presence of monosaccharides. It is based on the reduction of copper(II) acetate to copper(I) oxide (Cu2O), which forms a brick-red precipitate.RCHO + 2Cu2+ + 2H2O → RCOOH + Cu2O↓ + 4H+(Disaccharides may also react, but the reaction is much slower.) The aldehyde group of the monosaccharide which normally forms a cyclic hemiacetal is oxidized to the carboxylate. A number of other substances, including sodium chloride, may interfere.It was invented by Danish chemist Christen Thomsen Barfoed and is primarily used in botany.[citation needed]The test is similar to the reaction of Fehling's solution to aldehydes.. }
