What is an asymmetric carbon?
A carbon attached to four different atoms or groups of atoms.
How do small differences in sugars affect them?
They give the sugars distinctive shapes and binding activities, leading to different behaviors.
What are the two classifications of sugars based on the location of the carbonyl group?
- Aldoses (e.g., glucose, galactose)
- Ketoses (e.g., fructose)
What type of sugar is glucose?
Aldose.
What type of sugar is fructose?
Ketose.
What are trioses?

What are pentoses?
5-carbon sugars (C5H10O5).
What is ribose a component of?
