Simple Carbohydrates: Examples & Diagrams
-any 3 to 7 carbon in a molecule is a simple sugar called
a monosaccharide.
 Ex: Any Pentose (5-carbon sugar)
Deoxyribose found in DNA
Ribose  in RNA
 Ex: Any Hexose (6 carbon sugar)
Glucose in blood, cell’s main energy source
Fructose in fruits, sweetest of monomers
Glucose
Found in:
Blood
Used for:
Cell’s main energy
Source
Diagram:
Fructose
Found in:
Fruits
Used for:
Quick energy
Diagram:
Maltose
Found in:
Not often in natural food sources, made when
amylase breaks down starch
ex) carmelized glucose
Used for:
Energy
Diagram:
Disaccharides-contains two monosaccharides
Ex: maltose, sucrose
Ex: glucose + fructose = sucrose (table sugar)
 Examples of Polymers
 Starch –
 Found in: in plants
 Use for: storage form of glucose
 Diagram:
 GlycogenFound in: animals
Used for: storage forms of glucose
Diagram:
 Cellulose-
Found in: the cell walls of plants
Used for: provides structure & support
 Chitin -found in the cell
Walls of fungus and the
Exoskeleton of arthropods
Comparing Structural Diagrams of Polysaccharides:
1a) each point on the diagram except the O is a carbon -5
carbons circled in total
b) This is a Pentose sugar  made of 5 carbons
c) 3 examples of hexose sugars:
-glucose
-fructose
-galactose
d) Remember the general Molecular formula for a carb is
CnH2nOn soo….
glucose: C6H1206
pentose: C5H1oO5
e) A monosaccharide is made up of one sugar molecule, and
has 3-7 carbons in it. A disaccharide is made up of two sugar
molecules joined together and has more than 7 carbons.
 Both:
 Involve water
 Involve carbohydrates
 Involve chemical bonds (either formed or broken)
 Are reactions involved in cellular metabolism
