(a)
Interpretation: The total number of forms that exist for maltose in aqueous solution has to be predicted.
Concept introduction: Maltose is a disaccharide and it is also known as malt sugar. It is commonly found in baby foods and malted milk. Two glucose units are present in maltose joined together by
(b)
Interpretation: The total number of forms that exist for cellobiose in aqueous solution has to be predicted.
Concept introduction: Like maltose, cellobiose is a disaccharide and it contains two monosaccharide units of D-glucose joined together by
(c)
Interpretation: The total number of forms that exist for lactose in aqueous solution has to be predicted.
Concept introduction: Lactose is a disaccharide and it contains two monosaccharide units, D-galactose and D-glucose which are joined together by
(d)
Interpretation: The total number of forms that exist for sucrose in aqueous solution has to be predicted.
Concept introduction: Sucrose is a disaccharide and it contains two monosaccharide units, Fructose and Glucose. These monosaccharide units are joined together by
