Carbohydrates

Question	Answer
What are the three simple molecules of sugar? Monosaccharides	Glucose Galactose Fructose
Which are the three Disaccharides formed by the monosaccharides mentioned above?	Glucose + Glucose = Maltose Glucose + Galactose = Lactose Glucose + Fructose = Sucrose
Reducing Sugars	Glucose Galactose Fructose Lactose Maltose
Non Reducing Sugar	Sucrose
Test for Reducing Sugars	Add Benedicts solution. Heat it to 95 C. A coloured precipitate will form if reducing sugars are persent.
Test for Non Reducing Sugars	Take the sample in a test tube, add some HCl heat for 1 minute. Add Sodium Hydrogen Carbonate, to neutralize it. Carry out the benedicts test for Reducing sugar.
Reaction that forms Disaccharides fro Monosaccharides	Condensation
Reaction that forms Monosaccharides from Disaccharides	Hydrolysis
