Propose the plausible β structure of the disaccharide that contains two cyclic D-galactose sugars that are linked via the β-1,4 glycosidic bond. Explain why this disaccharide is a reducing sugar, while the sugar below is not reducing sugar.
Explain why cellobiose and lactose are considered reducing disaccharides, whereas the disaccharide trehalose is considered non-reducing.
Sucrose, a common disaccharide found in plants, can undergo hydrolysis. What monosaccharides would you obtain from this reaction?
Consider the disaccharides shown below:
Identify whether each is a reducing sugar or not.
Determine the disaccharide described below:
A disaccharide found in fungi that is used as a reserve energy source and aids in stress resistance.
Draw the Haworth structure for a hypothetical disaccharide that is quite similar to β-lactose except it has an α(1→4)−glycosidic bond.
Lactose, a carbohydrate found in milk, has the following structure:
What type of carbohydrate is lactose?
Lactose is a disaccharide found in milk. It is composed of two monosaccharides linked by a glycosidic bond. What are the monosaccharides present in lactose?
Given the following disaccharide:
(i) When the given disaccharide undergoes hydrolysis, determine the two monosaccharide units produced.
(ii) Determine the type of glycosidic bond that holds the disaccharide together.
(iii) Determine the name of the disaccharide and if it is α or ß.
Draw the Haworth structure for isomaltose, a disaccharide composed of two α-D-glucose molecules joined by an α(1→6)−glycosidic bond.
Determine if galactobiose is a reducing sugar. Explain your answer.
Cellobiose is a disaccharide obtained from the hydrolysis of cellulose, a polysaccharide found in plants. Based on its Haworth structure below, determine if it is an α- or β-anomer.
