Carbohydrates are organic compounds made up of carbon, hydrogen, and oxygen atoms. They are one of the main sources of energy for the human body and are found in a wide variety of foods, including fruits, vegetables, grains, and dairy products.
Carbohydrates can be classified into three main groups:
1. Monosaccharides: These are the simplest form of carbohydrates and consist of single sugar molecules. Examples include glucose, fructose, and galactose.
2. Disaccharides: These are carbohydrates made up of two monosaccharide units joined together. Examples include sucrose (glucose + fructose), lactose (glucose + galactose), and maltose (glucose + glucose).
3. Polysaccharides: These are complex carbohydrates made up of long chains of monosaccharide units. Examples include starch, glycogen, and cellulose.
Carbohydrates play several important functions in the body, including:
1. Providing energy: Carbohydrates are the body's primary source of energy and are broken down into glucose, which is used by cells for fuel.
2. Supporting brain function: Glucose is the main source of energy for the brain, and a steady supply of carbohydrates is essential for optimal brain function.
3. Promoting digestion: Dietary fiber, a type of carbohydrate found in plant foods, helps to promote healthy digestion and prevent constipation.
4. Supporting muscle function: Carbohydrates are important for fueling muscle contractions during exercise and physical activity.
Overall, carbohydrates are essential for overall health and well-being and should make up a significant portion of a balanced diet.

Definition of Carbohydrates
Carbohydrates are organic compounds composed of carbon, hydrogen, and oxygen, typically in the ratio of 1:2:1. They are classified based on their structure and complexity.
Classification of Carbohydrates
- Monosaccharides: Simple sugars with one sugar unit, e.g., glucose, fructose, galactose
- Disaccharides: Composed of two monosaccharides joined by a glycosidic bond, e.g., sucrose (glucose + fructose), lactose (glucose + galactose), maltose (glucose + glucose)
- Oligosaccharides: Contain 3-10 monosaccharide units, e.g., raffinose, stachyose
- Polysaccharides: Complex carbohydrates composed of many monosaccharide units joined by glycosidic bonds, e.g., starch, glycogen, cellulose
Functions of Carbohydrates
- Primary energy source: Glucose is the main source of energy for most living organisms.
- Structural components: Cellulose and chitin provide structural support to plant cell walls and animal exoskeletons, respectively.
- Storage of energy: Glycogen in animals and starch in plants serve as energy reserves.
- Signaling molecules: Carbohydrate chains attached to proteins and lipids play roles in cell recognition, adhesion, and immune function.
- Fiber: Non-digestible carbohydrates promote gut health and regularity.
