Interpretation: The classification of the given
Concept introduction: The simplest hydrolyzed form that is obtained from the carbohydrates is known as monosaccharide. Monosaccharide is categorized into two types. The first type of monosaccharide is aldoses and the second type of monosaccharide is ketoses. Aldoses sugar possesses
Monosaccharides are also classified on the basis of the number of carbon atoms present in it. For example, the sugar that contains five carbon atoms is known as pentoses sugar and the sugar that contains six carbon atoms is known as hexoses sugar.

- Identify each of the following Haworth projection formulas as an a-D monosaccharide or a ß D-monosaccharide.arrow_forwardDoes trehalose (Problem 20.68) have an acetal grouping? A hemiacetal grouping? Do you expect trehalose to be a reducing or nonreducing sugar? Classify the linkage between the two monosaccharides.arrow_forwardWhat is the structural difference between the monosaccharides glucose and galactose?arrow_forward
- Consider the following statements: (1) The term sugar is a general designation for both monosaccharides and disaccharides. (2) The "penultimate carbon" in a monosaccharide is used to determine D- or L-configuration. (3) Sucrose is a reducing sugar and lactose is a nonreducing sugar. O Two of the three statements are true. All three statements are true. O Only one of the statements is true. None of the statements are true.arrow_forward---is formed of a-glucose linked to B-fructose by (1,2 linkage). * Maltose O Lactose Sucrose Starcharrow_forwardAll naturally occurring polysaccharides have one terminal residue, which contains a free anomeric carbon. Why do these polysaccharides not give a positive chemical test for a reducing sugar?Please explainarrow_forward
- Raffinose (see prev. question for structure) is not digestible by humans yet is found in foods we eat all the time like beans, cabbage, brussels sprouts etc. What 2 human digestible compounds can Raffinose be broken down into? Just as a side note, Raff is NOT digestible by us, but our helpful gut bacteria break it down for us into the 2 compounds that are the answer to this question. O a-D-glucose O B-D-fructose sucrose a-D-galactose Lactose maltosearrow_forwardD- and L- designations are used to distinguish between the two possible enantiomers of the monosaccharide, galactose. From the Fischer projection, determine the designation of this monosaccharide.arrow_forwardDraw the Fischer projection for a monosaccharide.arrow_forward
