Carbohydrates Flashcards
What are carbohydrates used for?
Store and supply energy and can be used in structures
What is the general formula of a carbohydrate?
Cx (H2O)y
What is a monosaccharide?
This is a single sugar unit that can bond with others to become a polymer
What is a disaccharide?
When 2 monosaccharides are joined by a glycosidic bond through a condensation reaction
What is a polysaccharide?
When 3 or more monosaccharides are joined by a glycosidic bond
How many Carbon atoms in a triose?
3
How many Carbon atoms in a pentose?
5
How many Carbon atoms in a hexose?
6
Give an example of a triose
Glyceraldehyde
Give an example of a pentose
Deoxyribose and Ribose
Give an example of a hexose
Glucose and galactose
What is the general formula of triose?
C3 H6 O3
What is the general formula for a pentose?
C5 H10 05
What is the general formula for hexose?
C6 H12 06
What is a monosaccharide structure/features?
All white. crystalline solids which dissolve in water to give sweet tasting solutions
They are soluble in polar solvent
They are used for immediate energy, mainly hexose because of their large number of C-H bonds
Building blocks for larger molecule
What is a disaccharide structure/functions?
All white. crystalline solids which dissolve in water to give sweet tasting solutions
They are soluble in polar solvent
They are used for immediate energy, mainly hexose because of their large number of C-H bonds
Building blocks for larger molecule
What makes up a maltose?
2 alpha glucose
What makes up a sucrose?
1 alpha glucose and fructose
What makes up a lactose?
1 alpha glucose and 1 galactose
What makes up a cellulose?
2 beta glucose
