Monosaccharides and
Disaccharides

Introducing carbohydrates and monosaccharides:
Uses of carbohydrates:

Source and storage of energy

Strucutral function

Contain carbon, hydrogen and oxygen.


MONOSACCHARIDES (CH2O)n- single sugar monomers

Simplest carbohydrates- monomer building blocks for more complex
carbohydrates.
2 monosaccharides form a disaccharide
Many monosaccharides form a polysaccharide- carbohydrate polymer



No of carbon Type of sugar Molecular formula Example

3C Triose C3H6O3 glyceraldehyde

4C Tetrose C4H8O4 threose

5C Pentose C5H10O5 ribose

6C Hexose C6H12O6 glucose

Commonly found hexose molecules- fructose and galactose


Glucose:
