When Two Monosaccharides Undergo a Dehydration Synthesis

Question

When two monosaccharides undergo a dehydration synthesis,
A) two new monosaccharides are formed.
B) a disaccharide is formed.
C) a polysaccharide is formed.
D) a starch is formed.
E) hydrolysis occurs.

Accepted Answer

Dehydration synthesis is a chemical reaction in which two molecules are joined together with the removal of a water molecule. In the case of two monosaccharides undergoing dehydration synthesis, a covalent bond is formed between the two monosaccharides, resulting in the formation of a disaccharide. Therefore, the correct answer is B, a disaccharide is formed.
