What two monosaccharides make up sucrose?
A
glucose + galactose
B
glucose + fructose
C
glucose + glucose
D
fructose + maltose
Explanation: 

Detailed explanation-1: -Sucrose (table sugar) is the most common disaccharide, which is composed of the monomers glucose and fructose. A polysaccharide is a long chain of monosaccharides linked by glycosidic bonds; the chain may be branched or unbranched and can contain many types of monosaccharides.

Detailed explanation-2: -Sucrose is composed of glucose and fructose which is shown in Fig. 7.2.

Detailed explanation-3: -The three most common monosaccharides are glucose, fructose, and galactose. In addition to these three sugars, the monosaccharide category also includes sugar alcohols and pentoses.

Detailed explanation-4: -Disaccharides are formed when a dehydration reaction occurs between two monosaccharides. Notice that the two monosaccharide units are joined by an ether linkage. One of the most common disaccharides is sucrose, which is composed of one glucose and one fructose molecule.
