Question

Sucrose is a carbohydrate composed of two different sugar units (a.k.a. disaccharide). State and explain the process required to form a sucrose molecule. What is one key by-product of this process?

a) Glycolysis
b) Dehydration synthesis
c) Krebs cycle
d) None of the above

Answer 1

Sucrose is formed through dehydration synthesis, which involves the combination of glucose and fructose while removing a water molecule. Water is a key by-product of this process.

Step-by-step explanation:

The process required to form a sucrose molecule is called dehydration synthesis. In this process, a molecule of glucose and a molecule of fructose combine to produce a disaccharide sucrose. This reaction involves the removal of a water molecule. One key by-product of this process is water. As a water molecule is lost during the formation of the glycosidic bond between glucose and fructose, water is produced as a by-product.
