Study Notes
Carbohydrates
- Carbohydrates are a class of biomolecules that include sugars and polymers of sugars.
- Carbohydrates are used as a source of energy.
- Carbohydrates act as structural molecules in the cell wall of plants (cellulose) and the exoskeleton of crustaceans (chitin).
- Carbohydrates are organic compounds that primarily consist of carbon, hydrogen, and oxygen in a 1:2:1 ratio.
- Photosynthesis produces sugars, particularly glucose, for plant cells and other organisms.
- Cells oxidize glucose for energy to drive biochemical reactions.
Classifications of Carbohydrates
- Carbohydrates are classified according to their structure:
- Monosaccharides: simple sugars
- Oligosaccharides: two to ten monosaccharides
- Polysaccharides: hundreds to thousands of monosaccharides
Monosaccharides
- The monomers of carbohydrates that cannot be broken down further.
- Types include:
- Aldoses: contain an aldehyde group
- Ketoses: contain a ketone group
