Monosaccharide – Single sugar unit
5 – 6 carbons and 1 oxygen
Ring shape
Glucose most common
Building block to larger carbohydrates
C6H12O6
Biosynthesis – Dehydration Synthesis
• Chemical reactions used to form larger
molecules out of multiple smaller ones
• Ex. 2 monosaccharides joined to form a
disaccharide (2 sugars long)
Glucose + Fructose
Glucose + Galactose
Sucrose
Lactose
Dehydration Synthesis
Polysaccharides
• Multiple sugar units long
• Starch 100’s even 1000’s of glucoses long
• Cellulose – most abundant biomolecule on
earth…. Great source of fiber/roughage
• Glycogen – stored energy in animals in
liver and muscles
• About 3 days supply of energy
