1. Biochemistry Review

2. Main Topics
Organic Compounds
Enzymes
Solution and pH

4. Solution
Solution- Mixture of two substances where they cannot be separated
Solvent- What is doing the dissolving(water)
Solute- What is dissolved(sugar)
Suspension-Mixture of two substances where neither are dissolved(Dirt water)

5. Water 2 Hydrogen and 1 Oxygen Hydrogen bonds in between molecules
Covalent bonds within

6. Water continued Polar molecule Surface Tension Universal Solvent
Distinct positive and negative end
Surface Tension
Bonds are easy to break, but many of them are hard to break
Universal Solvent

7. pH pH scale- Measures acidity and basicity of a solution
8-14 Base
7 Neutral
Buffer-Weak acid or base used to control pH

8. Basic Biochemistry Organic Chemistry Monomers Polymers
All organic compounds contain carbon(C)!
Monomers
Building blocks of organic chemistry
Polymers
Macromolecules

9. Significant Macromolecules
Carbohydrates
Lipids
Proteins
Nucleic Acids

10. Proteins C, H, O, N Building for muscles and used as enzymes
Monomers- Amino Acids
Test- Biuret

11. Carbohydrates Three different forms
Monosaccharide-Glucose
Disaccharides-Sucrose
Polysaccharides-Starches
Contains Carbon, Hydrogen and Oxygen
Sugars
Provide quick energy

12. How to Test for Carbohydrates
Iodine
Color change from Orange to Rusty red
Benedicts solution
Color change from a sky blue to purple

13. Carbohydrates Review Slide
C, H, O
Quick Energy
Monomers- Monosaccharides
Glycogen
Iodine Test- Polysaccharides

14. Lipids C, H, O Insulation, Long term energy, improve eyes
Monomers- Fatty Acids and Glycerol
Test- Brown Bag Test

15. Nucleic Acids
C, H, O, N, P
Stores genetic material for living organisms
Monomer- Nucleotides
Phosphate group
Sugar
Nitrogen base
