Carbohydrates are organic compounds that consist of carbon (C), hydrogen (H), and oxygen (O) atoms, typically in a ratio of 1:2:1. The main organic chemical groups that characterize carbohydrates include:
1. **Hydroxyl Groups (-OH)**: These are the primary functional groups found in carbohydrates. Each carbohydrate molecule typically contains multiple hydroxyl groups, which are responsible for their solubility in water and contribute to their reactivity.
2. **Aldehyde Group (-CHO)**: Present in aldoses, a type of simple sugar (monosaccharide), the aldehyde group is located at the end of the carbon skeleton.
3. **Ketone Group (C=O)**: Present in ketoses, another type of monosaccharide, the ketone group is found within the carbon chain.
4. **Ester Linkages**: In some complex carbohydrates (e.g., glycoproteins and glycolipids), ester linkages can form between carbohydrates and fatty acids or amino acids.
These functional groups give carbohydrates their unique properties and behaviors and are fundamental to understanding how they interact in biological systems. Monosaccharides, disaccharides, oligosaccharides, and polysaccharides all contain these functional groups to varying extents, leading to a wide diversity of carbohydrate structures and functions.
