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.
