KEY TAKEAWAYS •
There are more than 200 monomer sugars, only a few of which are important in organic chemistry.
•
Sugars are carbon hydrates because every carbon atom but one has a hydroxyl group associated with it.
•
You should know the different common monosaccharides, disaccharides, and polysaccharides in nature.
•
The reactions of sugars involve the functional groups, mainly the hydroxyl group or the carbonyl group, which ultimately becomes an acetal or hemiacetal in most carbohydrate molecules.
