Identifying the Simplest Carbohydrate

Carbohydrates are essential biomolecules that serve various functions in living organisms, including energy storage and structural support. They are classified into three main categories: monosaccharides, oligosaccharides, and polysaccharides. Monosaccharides, the simplest form of carbohydrates, include glucose, fructose, and galactose. These simple sugars can combine to form more complex carbohydrates. This transformation is crucial for many biological processes.
