1.3 - Carbohydrates - Dissacharides and Polysaccharides Flashcards
1
Q
What is a disaccharide
A
Two monosaccharides joined in a pair
2
Q
Give 3 examples of discaccharides and which constituent monosaccharides are combined to form each disaccharide
A
Glucose + Glucose = Maltose
Glucose + Fructose = Sucrose
Glucose + Galactose = Lactose
3
Q
What bond is between two constituent monosacharides
A
1-4 Glycosidic bond
4
Q
What happens when two monosaccharides join
A
A molecule of water is removed and a chemical bond is formed
5
Q
How can a disaccharide be returned to its two constituent monosaccharides
A
Via the addition of water, breaking the glycosidic bond
6
Q
What is a polysaccharide
A
Polysaccharides are polymers formed by combining many monosaccharide molecules together via condensation reactions.
