Detailed explanation-1: -Hydrolysis. Polymers are broken down into monomers in a process known as hydrolysis, which means “to split water, ” a reaction in which a water molecule is used during the breakdown (Figure 3.1.
Detailed explanation-2: -In the dehydration synthesis reaction above, two molecules of the sugar glucose (monomers) combine to form a single molecule of the sugar maltose. One of the glucose molecules loses an H, the other loses an OH group, and a water molecule is released as a new covalent bond forms between the two glucose molecules.
Detailed explanation-3: -In a dehydration synthesis reaction between two un-ionized monomers, such as monosaccharide sugars, the hydrogen of one monomer combines with the hydroxyl group of another monomer, releasing a molecule of water in the process.
Detailed explanation-4: -Dehydration means the removal of the water molecules. Two monomer molecules undergo a dehydration reaction, which is a type of condensation reaction, to form polymer molecules with the removal of the water molecule as a by-product.
