Study Notes
Carbohydrates
- Carbohydrates are the main source of energy for the body.
- Carbohydrates are polyhydroxy aldehydes or ketones with multiple -OH groups.
- They can exist as long chains or ring structures.
- The general formula for carbohydrates is CnH2nOn, where "n" is the number of carbon atoms.
- Glucose, with six carbon atoms, has the formula C6H12O6.
- Carbohydrates are crucial components of nucleic acids like DNA and RNA.
- Ribose and deoxyribose are carbohydrates found in nucleic acids.
Subcategories of Carbohydrates
- Monosaccharides consist of a single sugar unit.
- Disaccharides consist of two sugar units.
- Oligosaccharides consist of three to ten sugar units.
- Polysaccharides consist of over ten sugar units.
Function of Carbohydrates
- Carbohydrates are the primary energy source for the body.
- Glucose reacts with oxygen to produce carbon dioxide, water, and energy.
- Carbohydrates make up approximately 75% of the dry weight of plants.
Chemical Structure of Carbohydrates
- Aldoses have an aldehyde group (H-C=O).
- Ketoses have a ketone group (C=O).
