1. Review Water is __________________
Attractive force between particles of the same kind. ____________________
Attractive force between unlike substances. _______________________
In a mixture of water and cool-aid which would be the solute and which would be the solvent?

2. What are the structure and function of the 4 macromolecules?
Section 6.4

3. Organic vs. Inorganic Organic Chemistry = carbon chemistry
Macromolecules are carbon based

4. Carbohydrates
Chemical composition: carbon, hydrogen, and oxygen in a 1:2:1 ratio
C6H12O6
Is C24H48O24 a carbohydrate?

5. Monosaccharides are monomers of carbohydrates.

6. Two monosaccharides= disaccharide

7. Many Monosaccharides= polysaccharide
Starch is a polysaccharide and plants store it as starch

9. Carbohydrates function in living things
Main source of energy in all living things

10. Nucleic Acids
Contains the 5 elements- Carbon, nitrogen, phosphorus, hydrogen, and oxygen
The monomers or building blocks of Nucleic Acids are nucleotides

11. Nucleotides are composed of. . .

12. Function in Living Things
- Stores hereditary information
Examples: DNA and RNA

13. Ticket out the Door
What is the chemical composition of carbohydrates and what is the ratio?
Give an example of a monosaccharide, disaccharide, and polysaccharide

14. Draw a picture of the monomer for nucleic acids.
What is the monomer for carbohydrates?
What 3 elements compose carbohydrates?
What are the two types of nucleic acids?
Tell me something you already know about lipids.

15. Building Blocks:
Lipids are made of fatty acids and glycerol.
Examples:
Phospholipids
Waxes
Triglycerides
Saturated
Unsaturated
Steroids
Hormones
Cholesterol

16. Why are lipids important?
Primary function is to store energy!
Waterproof covering (surfaces of leaves)
Protection (earwax)

17. Proteins Chemical Composition Carbon, hydrogen, oxygen and nitrogen
Building Blocks
Amino acids linked together by peptide bonds

18. Peptide Bond

19. Proteins
R-group in amino acids determine the structure of the protein.
1st- # of a.a. and their order
2nd- 3-D shape
3rd- Globular
4th- combine with other proteins

20. Why proteins are important
Function in Living Things: Skin and muscles are made largely of proteins
Enzymes are proteins.
Structural support of cells
Cell communication
Cell growth
