The monomers that are joined via dehydration synthesis reactions share electrons and form covalent bonds with each other. As additional monomers join via multiple dehydration synthesis reactions, this chain of repeating monomers begins to form a polymer. Complex carbohydrates, nucleic acids, and proteins are all examples of polymers that are formed by dehydration synthesis.
Monomers like glucose can join together in different ways and produce a variety of polymers. Monomers like mononucleotides and amino acids join together in different sequences to produce a variety of polymers. Key Terms covalent bond: A type of chemical bond where two atoms are connected to each other by the sharing of two or more electrons. Dehydration Synthesis Most macromolecules are made from single subunits, or building blocks, called monomers.
The monomers combine with each other via covalent bonds to form larger molecules known as polymers. In doing so, monomers release water molecules as byproducts. 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.
The removal of a hydrogen from one monomer and the removal of a hydroxyl group from the other monomer allows the monomers to share electrons and form a covalent bond. Thus, the monomers that are joined together are being dehydrated to allow for synthesis of a larger molecule.
A dehydration synthesis reaction involving un-ionized moners.. In the process, a water molecule is formed. In doing so, monomers release water molecules as byproducts. This type of reaction is known as dehydration synthesis, which means to put together while losing water.

As additional monomers join, this chain of repeating monomers forms a polymer. Different types of monomers can combine in many configurations, giving rise to a diverse group of macromolecules. Even one kind of monomer can combine in a variety of ways to form several different polymers; for example, glucose monomers are the constituents of starch, glycogen, and cellulose.
Hydrolysis Hydrolysis Polymers are broken down into monomers in a process known as hydrolysis, which means to split with water. Hydrolysis is a reaction in which a water molecule is used during the breakdown of another compound Figure 3. Note that this reaction is the reverse of the synthesis reaction shown in Figure 3.
Dehydration and hydrolysis reactions are catalyzed, or sped up, by specific enzymes: Dehydration reactions involve the formation of new bonds, requiring energy, while hydrolysis reactions break bonds and release energy. These reactions are similar for most macromolecules, but each monomer and polymer reaction is specific for its class. For example, in our bodies, food is hydrolyzed, or broken down, into smaller molecules by catalytic enzymes in the digestive system.
This allows for easy absorption of nutrients by cells in the intestine. Each macromolecule is broken down by a specific enzyme. For instance, carbohydrates are broken down by amylase, sucrase, lactase, or maltase. Proteins are broken down by the enzymes pepsin and peptidase, and by hydrochloric acid. Lipids are broken down by lipases. Breakdown of these macromolecules provides energy for cellular activities.

Sharing of electrons between monomers occurs in both dehydration synthesis and hydrolysis. The sharing of electrons between monomers occurs in hydrolysis only.
