Study Notes
Carbohydrates Importance
- Carbohydrates are crucial for life, providing energy through oxidation.
- Carbon from carbohydrates is used to build cell components.
- They act as a stored energy source.
- Carbohydrates form part of the structure of cells and tissues.
- Carbohydrates are biomolecules.
Carbohydrate Definition
- Carbohydrates, also called saccharides, are polyhydroxy aldehydes or ketones.
- They can break down into these compounds through hydrolysis.
Monosaccharides
- Monosaccharides are the simplest carbohydrates.
- They have a single polyhydroxy aldehyde or ketone unit.
- Examples include glucose and fructose.
Disaccharides
- Disaccharides consist of two monosaccharides linked by a covalent bond.
- An example is sucrose.
Oligosaccharides
- Oligosaccharides contain three to ten monosaccharide units.
- Raffinose is an example.
Polysaccharides
- Polysaccharides contain long chains of hundreds or thousands of monosaccharide units.
- These chains can be straight or branched.
- Examples include cellulose, glycogen, and starch.
