1. Biochemistry: Essentials for Life
Organic vs. Inorganic compounds

2. Important Inorganic Compounds
1. Water…….IS AMAZING!
60-80% of body……..Coincidence?
Vital Functions:

3. Journal
Based on lecture and AMAZING demos WHY is water found in such high amounts in the body?
Remember: structure determines function

4. Important Inorganic Compounds
2. Salts
- mostly Ca and P in bones and teeth

5. Important Inorganic Compounds
3. Acids and Bases
Neutralization Reaction
HCl + NaOH  NaCl + H2O
Homeostasis?

6. pH Scaled by increasing concentration of hydrogen ions (H+) - (10x’s)
pH 4 = 100 H+
pH 3 = 1000’s H+
Blood lab

7. Buffer Video:
Carbonic Acid-Bicarbonate Buffer

8. Quick Write
Give examples of inorganic substances and the role they have in the human body.

9. Important Organic Compounds
Carbohydrates
Monosaccharides
Disaccharides
Polysaccharides

10. Important Organic Compounds
Proteins

11. Proteins Account for over half of the body’s organic matter Functions:
Fibrous (structural) – collagen, keratin
Globular (communication) – antibodies, hormones
Catalysts – Enzymes
Membrane Transport – protein channels

12. Important Organic Compounds
Lipids

13. Common Lipids in Body
Plasma membrane/phospholipids
Fatty Acids

14. Lipids Lipids Cont’d Eicosanoid Steroids Triglycerides (Neutral Fats)
(prostaglandin)
Steroids
Triglycerides (Neutral Fats)
Lipids

15. Important Organic Compounds
Nucleic Acids
Chains of nucleotides

16. Examples of Nucleic Acids
Deoxyribonucleic acid (DNA)
Ribonucleic Acid (RNA)
Figure 2.18c

17. Important Organic Compounds
Adenosine triphosphate (ATP)

18. Simplified ATP Use Energy used to make ATP
Energy given off for cellular activities

19. How ATP Drives Cellular Work
