Carbs By: Jene Bright Tre Wright Michaela Armstrong Darien McNeill

Structural Form of Carbs

What are carbs? Carbohydrates, or saccharides, are the most abundant of the four major classes of biomolecules. They fill numerous roles in living things, such as the storage and transport of energy (e.g., starch, glycogen) and structural components (e.g., cellulose in plants and chitin in animals).

In addition… Carbohydrates and their derivatives play major roles in the working process of the immune system, fertilization, pathogenesis, blood clotting, and development. Carbohydrates are simple organic compounds that are aldehydes or ketones with many hydroxyl groups added, usually one on each carbon atom that is not part of the aldehyde or ketone functional group.

More information… The basic carbohydrate units are called monosaccharides; examples are glucose, galactose, and fructose. The general stoichiometric formula of an unmodified monosaccharide is (C·H2O)n, where n is any number of three or greater; however, not all carbohydrates conform to this precise stoichiometric definition (e.g., uronic acids, deoxy-sugars such as fructose), nor are all chemicals that do conform to this definition automatically classified as carbohydrates

Monosaccharides Monosaccharides can be linked together into what are called polysaccharides in a large variety of ways. Many carbohydrates contain one or more modified monosaccharide units that have had one or more groups replaced or removed. For example, deoxyribose, a component of DNA, is a modified version of ribose; chitin is composed of repeating units of N-acetylglucosamine, a nitrogen-containing form of glucose.

Other information… While the scientific nomenclature of carbohydrates is complex, the names of carbohydrates very often end in the suffix -ose. Glycoinformatics is the specialised field of study that deals with the specific and unique bioinformatics of carbohydrates.
