Maltose in barfoed's test

WebA Barfoed’s test was used to distinguish reducing monosaccharides from disaccharides by controlling pH and time heating. A different carbohydrates was used to test in the barfoed’s reagents such as; glucose, galactose, fructose, xylose, maltose, sucrose and distilled water. WebQuestion: Test for Carbohydrates (monosaccharides, disaccharides and polysaccharides) 1.You are given the following carbohydrates: glucose , maltose, sucrose and starch. Explain thr results describe below. (a) A carbohydrate solution gave a negative Benedict's, Barfoed's, Bial's and Seliwanoff's tests.
