1. Macromolecules in Cells
Biology Standards 1 a and b

3. You can be a biologist too!

4. Cell: is the smallest unit of life.
Introduction
Biology: study of life.
Cell: is the smallest unit of life.
100,000,000,000 cells.

8. 1. Inorganic compounds- contain no C, Carbon, in them. Ex: H20 (water)
Chemical Compounds
2 types found in cells
1. Inorganic compounds- contain no C, Carbon, in them. Ex: H20 (water)

9. Salt-Sodium Chloride, NaCl

10. 2nd type: Organic Compounds: contain Carbon in them.
Chemical Compounds
2nd type: Organic Compounds: contain Carbon in them.
Ex: C6H12O6 (glucose)

11. Methane-CH4 AKA Natural Gas

12. Polymerization Small join to form bigger compounds.
Smaller compounds: monomers.
Larger compounds: polymers (macromolecules)

13. O Compounds: Carbohydrates
Sugars, starches, fibers
Made up of C, H, and O.
Simple carb’s  monosaccharides.
Complex carb’s  polysaccharides.

14. O Compounds: Carbohydrates Dehydration Synthesis
Polysaccharides formed by dehydration synthesis [water is released]
Dehydration Synthesis
C6H12O6 + C6H12O6  C12H22O11 + H2O
Glucose + glucose  sucrose + water

15. Dehydration Synthesis Video

16. Opposite is Hydrolysis: water is used when molecules break apart

17. O Compounds: Lipids Lipids: waxes or oils. AKA Fats! C, H, O
Store energy, form membranes, and can be messengers.
Formed from fatty acid chains and glycerol

18. Fatty Acid and Glycerol

19. Saturated vs. Unsaturated Lipids
Saturated Lipid: every carbon in the fatty acid chain is joined to another carbon atom by a single bond.
Unsaturated Lipid: one carbon is double bonded to another carbon.

21. High in Saturated Fats!

22. High in Unsaturated Fats!

23. High in Saturated Fats!

24. High in Unsaturated Fats!
