- A) Define "reducing sugar." (b) Sucrose is a disaccharide composed of glucose and fructose (Glc(1 → 2)Fru). Explain why sucrose is not a reducing sugar, even though both glucose and fructose are.arrow_forwardWhich statement about saccharides is correct? (A). Alpha anomers are more common than beta anoomers. (B). Two monosaccharides can form a disaccharide and oxygen. (C). Polysaccharides with alpha or beta glycosidic linkages have the different properties. (D). Disaccharides can be cyclic or acyclic.arrow_forwardMonosaccharides can be categorized in terms of thenumber of carbon atoms (pentoses have five carbons andhexoses have six carbons) and according to whether theycontain an aldehyde (aldo- prefix, as in aldopentose) orketone group (keto- prefix, as in ketopentose). Classify glucoseand fructose in this way.arrow_forward
- Indicate whether each statement is true or false: (a)Disaccharides are a type of carbohydrate. (b) Sucrose is amonosaccharide. (c) All carbohydrates have the formulaCnH2mOm.arrow_forwardIf a monosaccharide is represented by a single blue sphere, which of the following representations corresponds to (a) lactose; (b) cellulose; (c) amylopectin?arrow_forwardSuggest how you could distinguish a sample of glucose from a sample of maltose using Benedict’s reagent. [Hint: maltose is a disaccharide reducing sugar].arrow_forward
