1. Biochemistry

2. What Makes Something Organic?
Carbon & Hydrogen!

3. Why is Carbon Important?
Carbon: Organic compound serves as basis for life
4 valence electrons
Ability for covalent bonding
with other elements
May also bond with itself
Single, double, triple bond
Forms rings of carbon
Form long chains of carbons

4. Functional Groups Carboxyl Ketone Hydroxyl Amino C=O N-H-H -OH group
C=O-OH

5. Parts of the chemical reaction
Chemical Reactions
Chemical Reactions: Energy and matter (atoms) are neither created nor destroyed- they are rearranged
Parts of the chemical reaction
Large numbers in front of molecular formulas: # of those compounds in reaction
Reactants: Left side; molecules put into the reaction
Arrow: Represents the reaction itself
Products: Right side; result of the reaction

6. Vocabulary: Monomers versus Polymers
Monomer- 1 single molecule
Polymer- more than 1 single molecule joined together

7. Types of Chemical Reactions
Dehydration Synthesis- join monomers together; water is an end product

8. Types of Chemical Reactions
Hydrolysis- Put water into the equation to break apart the disaccharide or polysaccharide

9. Remember: Dehydrate to make, hydrate to break!

10. Endothermic and Exothermic Reactions
Endothermic- heat put into the reaction
Exothermic- heat released from the reaction
Dehydration Synthesis Endothermic
Creating bonds requires energy
Hydrolysis Exothermic
Breaking bonds releases energy
