Therefore, condensation is a reaction where water is removed and a polymer is formed. The most well-known disaccharide found in nature is sucrose, which is also called cane sugar, beet sugar or table sugar (see Figure 1C). The oxygen atom in the water molecule has two lone pairs, one of which could be used to form a bond with an (H +), and, therefore, the water molecule could act as a base in a reaction. Since water has the potential to act both as an acid and as a base, water is amphoteric. Amphoteric behavior means the substance can react with both acid and base. Jul 10, 2007 · 2.
