2.1.2: Monosaccharides Flashcards
(22 cards)
What is a monosaccharide?
A simple sugar that cannot be hydrolyzed to a simpler sugar.
What is the molecular formula of glucose?
C6H12O6
What are the two structural isomers of glucose?
- α-glucose
- β-glucose
What type of sugar is glucose classified as?
Hexose sugar
What is the role of glucose in organisms?
- Provides energy
- Can be polymerised to form structural support molecules
- Can be polymerised to form energy storage molecules
What are the energy storage molecules formed from glucose?
- Glycogen
- Starch
How many carbon atoms are present in glucose?
6
In what way do structural isomers differ?
They have the same molecular formula but different arrangements of atoms.
What changes occur between α-glucose and β-glucose?
The positions of the hydrogen (H) and hydroxyl group (OH) on carbon atom 1 are swapped.
