The monomer for carbohydrate is a monosaccharide. The elements it contains are oxygen, hydrogen, and carbon. The monosaccharide has a distinct ring shape, which is usually a pentagon or hexagon.

Chemical Composition

The elements in a monosaccharide are carbon, oxygen, and hydrogen. The oxygen atom has 8 protons, 8 electrons, and 8 neutrons. The carbon atom has 6 electrons, 6 protons, and 6 neutrons. The hydrogen atom has 1 electron, 1 proton, and 0 neutrons.


The carbohydrate has many roles. It's most important role is to provide short-term, instant energy for many body processes, such as brain function, physical activity, and functionality of organs. Another role carbohydrate places is as an aid in processing fat. The oxaloacetic acid created by carbohydrates is a necessary component of metabolizing fat. Lastly, it is a part of many important cells and structures in our body such as the antibodies. Antibodies are a collection of protein and carbohydrates that will only function properly with both biomolecules present.


An example of a carbohydrate is glucose. Glucose has a hexagonal shaped ring that is made up of compounds that include carbon, oxygen, and hydrogen. Glucose plays an important role in metabolism. It is the energy source for many organs in our body. Many of these organs can use lipids or proteins if necessary, but a few organs, like the brain, can only use glucose for energy. Glucose is stored in the body as glycogen.
