Understand the structural basis of carbohydrates: Carbohydrates are organic molecules composed of carbon, hydrogen, and oxygen, typically in the ratio (CH₂O)n. Their classification is based on the number of sugar units they contain.

Learn the three primary classifications: Carbohydrates are categorized into monosaccharides (single sugar units), oligosaccharides (a few sugar units, typically 2-10), and polysaccharides (many sugar units). This classification is structural and reflects the complexity of the molecule.

Monosaccharides: These are the simplest form of carbohydrates, consisting of a single sugar unit. Examples include glucose, fructose, and galactose. They serve as building blocks for more complex carbohydrates.

Oligosaccharides: These are composed of 2-10 monosaccharide units linked by glycosidic bonds. Examples include disaccharides like sucrose (glucose + fructose) and lactose (glucose + galactose). They play roles in energy storage and cellular communication.

Polysaccharides: These are large, complex carbohydrates made up of many monosaccharide units. Examples include starch, glycogen, and cellulose. They serve as energy storage molecules or structural components in cells.
