Study Notes
- Carbohydrates are macromolecules consisting of C, H, and O.
- They are essential components of all living organisms.
- Carbohydrates provide energy, store energy, and supply carbon atoms for the synthesis of other biochemical substances.
- They can be classified as monosaccharides, disaccharides, oligosaccharides, and polysaccharides.
- Monosaccharides are the simplest group of carbohydrates and cannot be further hydrolyzed.
- Monosaccharides can be aldoses or ketoses and can have different numbers of carbon atoms.
- Monosaccharides can exist in different forms, including cyclic forms and anomers.
- Cyclic forms are in equilibrium with open chain forms.
- Anomers are cyclic monosaccharides that differ only in the position of the substituents on the anomeric carbon atom.
- Glucose has 16 stereoisomers due to its 4 chiral centers.
