Disaccharides And Polysaccharides Flashcards
What is a monosaccharide?
The simplest form of carbohydrates.
What are disaccharides?
Two monosaccharides covalently linked by a glycosidic bond formed by a condensation reaction; removal of water.
What are the 3 properties of disaccharides?
- Sweet tasting
- Soluble in water
3.osmotically active
Why are disaccharides osmotically active?
They are soluble
What does osmotically active mean?
Can carry out osmosis
What affects the ratio of C : H : O?
The loss of water.
Are disaccharides reducing sugars?
Most for example, maltose and lactose
Which disaccharide is not a reducing sugar?
Sucrose
What are the 3 common disaccharides?
- Sucrose (sugar)
- Lactose (milk sugar)
- Maltose (malt sugar)
What is the function of sucrose?
Energy transport and storage in plants.
What is the enzyme the breaks down sucrose?
Sucrase
What is the function of lactose?
Energy transport and storage in mammal milk.
What is the enzyme that breaks down lactose?
Lactase
What is the function of maltose?
Intermediate in starch digestion
What is the enzyme that breaks down maltose?
Maltase
What are oligosaccharides?
Chains of monosaccharides that are covalently linked to one another by glycosidic bonds.
