Biochemistry
2
Macromolecules (large molecules): Carbohydrates Lipids Proteins Nucleic Acids These are Polymers ( many parts) constructed of Monomers (single part)
3

5
monomer
6
How to Connect Monomers- Hydrolysis- Breaking apart polymer Adding water molecule
7
Connecting Monomers- Dehydration reaction Hydrolysis- Breaking apart polymer Adding water molecule
8
Connecting Monomers- Dehydration reaction joining monomers loss of water molecule Hydrolysis- Breaking apart polymer Adding water molecule
9
Connecting Monomers- Dehydration reaction joining monomers loss of water molecule Hydrolysis- Breaking apart polymer Adding water molecule
10
Connecting Monomers- Dehydration reaction this takes energy Hydrolysis- Breaking apart polymer Adding water molecule
11
Connecting Monomers- Dehydration reaction this means energy must be added in order for the reaction to occur Putting together
12
Hydrolysis- Breaking apart polymer Adding water molecule Breaking apart polymers Hydrolysis- (break w/ water) Adding water molecule
13
Hydrolysis- Breaking apart polymer Adding water molecule Breaking apart polymers Hydrolysis- (break w/ water) Adding water molecule
14
Hydrolysis- Breaking apart polymer Adding water molecule Breaking apart polymers Hydrolysis- (break w/ water) Adding water molecule
15
Hydrolysis- Breaking apart polymer Adding water molecule Breaking apart polymers Hydrolysis- (break w/ water) Adding water molecule
16
Creating Monomers- Hydrolysis reaction this gives off energy when this happens breaking up
17
Hydrolysis- Breaking apart polymer Adding water molecule explain to your partner what is happening

Macromolecules (large molecules): Carbohydrates Lipids Proteins Nucleic Acids
20
Carbohydrates- Fuel - stores energy functions : Building material - > in plants in animals in plants = cellulose (cell wall) in animals = chitin (insect/ lobster covering)
21
Carbohydrates- types:
22
1)Monosaccharides Single Sugar
23
Monosaccharides Structure: Single Sugar Function: Fuel for cell work ex. glucose - blood sugar fructose - fruit sugar lactose - ??
24
Monosaccharides - structure: multiple of CH 2 O ex. glucose C 6 H 12 O 6
25
Disaccharides Two sugar monomers joined by dehydration synthesis
26
Disaccharides Two sugar monomers joined by dehydration synthesis - JOIN / SPIT OH-
27
Disaccharides Two sugar monomers joined by dehydration synthesis ex. sucrose - table sugar
28
Polysaccharides Many monomers
29
Polysaccharides Many monomers Functions: 1) Energy storage= starch starch (plant) glycogen (animal)
30
Polysaccharides Many monomers Functions: 1) Energy storage= 2) Structural support = cellulose
31
Polysaccharides 2) Structural support = cellulose
33
Macromolecules (large molecules): Carbohydrates Lipids Proteins Nucleic Acids
34
Lipids- Types: 11) Fat~ triglyceride 22) Phospholipid~ cell membranes 33) Steriod 44) Wax
35
Lipids- Structure = have a higher ratio of C & H than Oxygen
36
They HATE water Therefore, are they polar or nonpolar?
37
Lipids- (hydrophobic) 1111) Fats (triglyceride) - functions: -energy storage -cushion internal organs -insulation
38
Types of Lipids: Fats- structure 11 Glycerol FFatty acid chain = hydrophobic Energy storage Cushion
39
Types of Lipids: Fats- structure Glycerol Fatty acid chain = hydrophobic Energy storage Cushion +3 fatty acid chains

41
2)Phospholipids- 2)Phospholipids- structure 1 hydrophilic head 2 hydrophobic tails
42
2)Phospholipids- 2)Phospholipids- structure 1 hydrophilic head 2 hydrophobic tails
43
3) Steroids - 4 Fused (connected) “rings” cholesterol, testosterone, estrogen
44
4) Wax - Long CH 2 chain
46
Macromolecules (large molecules): Carbohydrates Lipids Proteins Nucleic Acids
47
Proteins- Monomer = amino acid Polymer of amino acids = polypeptides-
48
Proteins- function depends on shape: 1)support 2)structure 3) enzymes
49
Amino Acids = monomer 20 types 20 types
50
Amino Acids C R(VARIABLE) H Carboxyl COOH amino group NH 2 20 types 20 types
51
Amino Acids C R H carboxyl amino group 20 types 20 types 20 varying molecules
52
Proteins- - precise sequence of amino acids. amino - - carboxyl group group
53
Sequence of amino acids determines HOW the protein works
54
Shape determine s how the protein works
55
Macromolecules (large molecules): Carbohydrates Lipids Proteins Nucleic Acids
56
Nucleic Acids- DNA RNA Programs ALL organism function
57
Nucleic Acids- Composed of: nitrogen base, sugar, phosphate group = NUCLEOTIDE
58
DNARNA
