Because of this small difference, they differ structurally and chemically and are known as chemical isomers because of the different arrangement of functional groups around the asymmetric carbon; both of these monosaccharides have more than one asymmetric carbon (compare the structures in the figure below).

Carbohydrates are used to provide or store energy, among other uses. Like most biochemical compounds, carbohydrates are built of small repeating units, or monomers, which form bonds with each other to make larger molecules, called polymers. In the case of carbohydrates, the small repeating units are known as monosaccharides.

From a chemical viewpoint, carbohydrates are primarily a combination of carbon and water, and many of them have the empirical formula (CH2O)n, where n is the number of repeated units. This view represents these molecules simply as “hydrated” carbon atom chains in which water molecules attach to each carbon atom, leading to the term “carbohydrates.”

Carbohydrates provide energy to the body, particularly through glucose, a simple sugar that is a component of starch and an ingredient in many staple foods. Carbohydrates also have other important functions in humans, animals, and plants.

It discusses the classification into homopolysaccharides (e.g., starch, glycogen, cellulose) and heteropolysaccharides (e.g., glycosaminoglycans), emphasizing the impact of glycosidic linkages on structure and function. Key polysaccharides like amylose, chitin, and peptidoglycan are examined in terms of biological significance.

It details monosaccharides like glucose, galactose, and fructose, which combine into disaccharides like sucrose and lactose through glycosidic bonds. Carbohydrates are key energy sources in diets. Starch is formed in amylose (linear) and amylopectin (branched) forms, while cellulose serves a structural role in cell walls with its rigid fibrils.

Starch is the stored form of sugars in plants and is made up of a mixture of amylose and amylopectin (both polymers of glucose).

Combined, these molecules make up the majority of a cell’s mass. Biological macromolecules are organic, meaning that they contain carbon (with some exceptions, like carbon dioxide).
