1. Carbohydrates are organic compounds made up of carbon, hydrogen, and oxygen atoms.
2. They are the body's main source of energy and are essential for proper functioning of the brain, muscles, and other organs.
3. Carbohydrates can be classified into three main types: sugars, starches, and fiber.
4. Sugars are simple carbohydrates that provide quick energy, while starches are complex carbohydrates that provide sustained energy.
5. Fiber is a type of carbohydrate that cannot be digested by the body, but is important for maintaining digestive health.
6. Carbohydrates are found in a wide variety of foods, including fruits, vegetables, grains, and dairy products.
7. Excess consumption of carbohydrates, especially refined sugars and starches, can contribute to weight gain and other health problems.
8. Carbohydrates are often measured in terms of their glycemic index, which indicates how quickly they raise blood sugar levels.

General Characteristics:
- Biomolecules: Composed of carbon, hydrogen, and oxygen atoms.
- Polymers: Made up of multiple repeating units (monosaccharides or oligosaccharides) linked by glycosidic bonds.
- Polar: Contain hydroxyl groups, which make them water-soluble.
Major Types:
- Monosaccharides: Simple sugars cannot be broken down further by hydrolysis (e.g., glucose, fructose, galactose).
- Oligosaccharides: Carbohydrates containing 2-10 monosaccharides linked together (e.g., sucrose, lactose, maltose).
- Polysaccharides: Complex carbohydrates composed of long chains of monosaccharides (e.g., starch, glycogen, cellulose).
Physical and Chemical Properties:
- Taste: Sweetness varies depending on the structure and type of carbohydrate.
- Melting point: High melting points for solid polysaccharides due to their complex structures.
- Solubility: Polar monosaccharides and oligosaccharides are water-soluble. Complex polysaccharides may be insoluble depending on their structure.
- Reactivity: Carbohydrates can undergo chemical reactions such as glycosylation, phosphorylation, and hydrolysis.
Biological Functions:
- Energy storage: Polysaccharides (e.g., starch, glycogen) serve as energy reserves.
- Energy metabolism: Monosaccharides (e.g., glucose) are the primary source of energy for cells.
- Structural components: Polysaccharides (e.g., cellulose, chitin) provide structural support in plant cell walls and animal exoskeletons.
- Cell-cell recognition: Oligosaccharides (e.g., glycoproteins, glycolipids) play a role in cell-cell interactions and recognition.
- Hormone regulation: Some carbohydrates (e.g., glycoproteins) act as hormones or cofactors for enzymes.
Additional Characteristics:
- Chiral: Carbohydrates are chiral molecules, meaning they exist in enantiomers (mirror images).
- Reducing and non-reducing: Carbohydrates with free anomeric carbon atoms (monosaccharides and some oligosaccharides) are reducing agents.
- Glycosylation: Carbohydrates can be attached to proteins or lipids to form glycoproteins or glycolipids, respectively.
- Biomolecules: Composed of carbon, hydrogen, and oxygen atoms.
- Polymers: Made up of multiple repeating units (monosaccharides or oligosaccharides) linked by glycosidic bonds.
