1. Biochemistry

2. Carbohydrates Class of organic compounds contains C, H, O
monosaccharides
C6H12O6
hexoses
glucose
galactose
fructose

3. One way to represent glucose
Aldehyde

4. Another way to represent glucose
When glucose is placed into water it takes on a cyclic structure

5. Fructose
Ketone 2

6. Polymerization When small subunits are joined into longer compounds
When monosaccharides are in cyclic form they can bond together in looooong chains
many monosaccharides bonded together =
polysaccharide

7. Polymerization of monosaccharides
Cellulose
starch
chitin

8. Polymerization Condensation polymerization
C6H12O C6H12O C12H22O H2O

9. Polymerization of carbs
disaccharide
monosaccharide
polysaccharide

10. Importances Of Carbohydrates
Sources of Energy
oxidation of glucose
Aerobic Cellular respiration
∆H = + or - ?
Exothermic / Endothermic?
Occurring in the
presence of oxygen
C6H12O6 + 6O2 6H2O + 6CO2
36 ATP

11. Impt #2 Fermentation C6H12O6 2C2H5OH + 2CO2 anaerobic respiration
Occurs without oxygen
Fermentation
anaerobic respiration
process occurs with yeast
2 ATP
C6H12O C2H5OH CO2

12. Lipids a.k.a. Fats
Monomers
3 fatty acids
1 glycerol

13. condensation polymerization
HOH
condensation polymerization
HOH
HOH

15. tightly packed together
Made up of saturated
hydrocarbon chains
tightly packed together
Made up of unsaturated
branched “flowing”
hydrocarbon chains
