Carbohydrates can be classified based on the presence of organic chemical groups into several categories. The main classifications are:
1. **Monosaccharides**: These are the simplest carbohydrates and consist of single sugar molecules. They generally contain functional groups such as aldehydes (making them aldoses) or ketones (making them ketoses). Examples include:
- Glucose (an aldohexose)
- Fructose (a ketohexose)
- Ribose (an aldopentose)
2. **Oligosaccharides**: These are carbohydrates composed of 2 to 10 monosaccharide units linked by glycosidic bonds. They can be further classified based on the types of monosaccharides involved and the position of the glycosidic bond. Common types include:
- Disaccharides: Composed of two monosaccharides (e.g., sucrose, lactose).
- Trisaccharides: Composed of three monosaccharides (e.g., raffinose).
3. **Polysaccharides**: These consist of long chains of monosaccharide units (more than 10) and can be classified further based on their structure and function:
- Homopolysaccharides: Made up of the same type of monosaccharide (e.g., starch and glycogen, which are polymers of glucose).
- Heteropolysaccharides: Composed of different kinds of monosaccharides or sugar derivatives (e.g., hyaluronic acid).
4. **Due to Functional Groups**: Carbohydrates can also be defined based on the presence of specific functional groups:
- **Aldoses**: Contain an aldehyde group (-CHO) at the end of the sugar molecule.
- **Ketoses**: Contain a ketone group (C=O) usually at the second carbon.
By understanding these classifications, you can see how carbohydrates differ in structure, reactivity, and biological function based on their organic chemical groups.
