Study Notes
Carbohydrates
- Most abundant components produced by plants
- Are aldehyde or ketone derivatives with a general formula of $C_nH_{2n}O_n$
- Composed of 3 or more carbon atoms
- Found in sources such as bread, potatoes, milk, beans, corn, and soft drinks
Importance of Carbohydrates
- Primary energy source
- Energy storage: starch in plants, glycogen in animals and humans (liver & muscles)
- Provide carbon for synthesis of other compounds
- Key component of nucleic acids
- Form blood groups
- Biological roles include hormones and enzymes
- Structural components in plants and animals
Classification of Carbohydrates by Sugar Units
- Monosaccharides: Simple sugars with one sugar unit
- Disaccharides: Two monosaccharides
- Oligosaccharides: 3 to 10 sugar units
- Polysaccharides: More than 10 monosaccharides
Monosaccharides
- Can be categorized by the number of carbon atoms:
- 3: Triose
- 4: Tetrose
- 5: Pentose
- 6: Hexose
- 7: Heptose
- Can be categorized by the active group:
- Aldoses: The carbonyl group is at the end of the carbon chain.
- Ketoses: The carbonyl group is in the middle of the carbon chain.
- Aldotriose:
- Glyceraldhyde
- Aldotetrose:
- Erythrose
- Aldopentose:
- Ribose
- Aldohexose:
- Glucose
- Galactose
- Aldoheptose:
- Heptose
- Ketotriose:
- Dihydroxyacetone
- Ketotetrose:
- Erythrulose
- Ketopentrose:
- Ribulose
- Ketohexose:
- Fructose
- Ketoheptose:
- Heptulose
