Cynthia has taught high school science courses for many years and has a Master of Science degree and a Master of Arts in Teaching. There are many types of plastics, but all of them are made through a process called polymerization, the joining of monomer units to form the plastic polymers. During these reactions, the polymer is broken into two components: one part gains a hydrogen atom (H+) and the other gains a hydroxyl molecule (OH–) from a split water molecule. Review the following table for some important examples of these types of biological polymers (see video). DNA is shown in the following image. Because macromolecules are made of many building blocks, called monomers, you can see why these terms are synonymous. We’d love your input. To learn more, visit our Earning Credit Page. Glucose is a monosaccharide that is essential for energy production needed for all cellular processes. Sort by: Top Voted. Macromolecules are particularly large molecules that contain a lot of atoms. All rights reserved. Elastomers are macromolecules that are stretchy and very flexible. Nucleic acids and carbohydrates are both types of what?

Polymers may be prepared from inorganic matter as well as for instance in inorganic polymers and geopolymers. These macromolecules are polar [polar: having different ends] because they are formed by head to tail condensation of polar monomers. You were using small units to make a larger object using these small units over and over until you got the bigger item you wanted to construct. and career path that can help you find the school that's right for you. This type of reaction is known as dehydration synthesis, which means “to put together while losing water.”. Most macromolecules are made from single subunits, or building blocks, called monomers. You may be wondering if you've ever encountered a macromolecule. Another term for a macromolecule is a polymer. Simply stated, molecules are a collection of a group of one or more atoms with the same element that are joined to each other with chemical bonds as based on the valence electrons of each of the atoms. The nucleic acid that you are most familiar with is DNA. When polymers are broken down into smaller units (monomers), a molecule of water is used for each bond broken by these reactions; such reactions are known as hydrolysis reactions. This allows for easy absorption of nutrients by cells in the intestine. Foods that contain carbohydrates, lipids, proteins and nucleic acids make up a balanced diet. 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. There are three important … first two years of college and save thousands off your degree.
