1. Carbohydrates
Classification

2. Carbohydrates
• There are a variety of interrelated classification schemes.
• The most useful classification scheme divides the carbohydrates
into groups according to the number of individual simple sugar
units.
• MonosaccharidesMonosaccharides contain a single unit;
• disaccharidesdisaccharides contain two sugar units; and polysaccharidespolysaccharides
contain many sugar units as in polymers - most contain glucose
as the monosaccharide unit.

3. Carbohydrates
Monosaccharides Disaccharides Polysaccharides
Glucose Sucrose Starch
Galactose Maltose Glycogen
Fructose Lactose Cellulose
Ribose
Glyceraldehyde

4. Monosaccharides
Glucose
Galactose Greek word for milk--"galact", found asa
component of lactosein milk.

5. Disaccharides

6. Polysaccharides

7. Number of Carbons:
• Monosaccharides can be further classified by the number of
carbons present.
• Hexoses (6-carbons) are by far the most prevalent.
Six = Hexose Five = Pentose Three = Triose
Glucose Ribose Glyceraldehyde
Galactose
Fructose
