Monosaccharides

Simple sugars that cannot be broken down further by hydrolysis.

Glucose

Glucose is a monosaccharide that is a primary source of energy for the body.

Disaccharides

Sugars composed of two monosaccharides joined by a glycosidic bond.

Study Notes

Monosaccharides include glucose, fructose (fruit sugar), and galactose.
Disaccharides include sucrose (table sugar, sweeteners), maltose, and lactose (milk sugar).
Polysaccharides include glycogen, which is the storage form of sugar in animals.
Starch, a polysaccharide, acts as the storage form of sugar in plants.

Description

This lesson explores the three main types of carbohydrates: monosaccharides, disaccharides, and polysaccharides. It identifies common examples of each, such as glucose and fructose for monosaccharides, sucrose and lactose for disaccharides, and glycogen and starch for polysaccharides. The functions of glycogen and starch as storage forms of sugar are discussed.
