Topic

• Intro to Biomacromolecules

3
Objective

• Describe the structure and function of the four
  groups of biomacromolecules

4
The Stuff of Life
5
Introduction

• All living things made of chemicals
• C, H, O, N
• P, S
• Others

6
Carbon Organic Chemistry

• Forms 4 covalent bonds
• Energy is stored in covalent bonds
• Carbon can form large stable chains or rings or
  chains of rings

7
Polymerization

• Many small molecules, monomers, are joined
  together to form very large molecules called
  polymers.
• Really, really, really large molecules are called
  macromolecules.
• Define Biomacromolecules.

8
Carbohydrates

• Examples
• Functions
• Energy
• structure

9
Carbohydrates

• Monomers monosaccharides
• Ex. Glucose

10
Dehydration Synthesis
Monosaccharides
Disaccharide
Polysaccharide
11
Dehydration / Hydrolysis
12
Dehydration synthesis

• Small molecules are joined together to form
  larger molecules
• Energy is used
• Water is released

H2O
13
Dehydration synthesis

• Small molecules are joined together to form
  larger molecules
• Energy is used
• Water is released

14
Hydrolysis

• Large molecules are broken apart to produce
  smaller molecules
• Energy is released
• Water is used to split the bond

H2O
15
Hydrolysis

• Large molecules are broken apart to produce
  smaller molecules
• Energy is released
• Water is used to split the bond

Lipids

• Examples
• Function
• Energy
• Protection
• Cell membrane

18
Monomers/polymers

• Fatty acids glycerol gt Triglyceride
• Saturated vs. unsaturated
• Phospholipids

19
Protein

• Examples
• Function
• Structure
• Enzymes catalyze, speed-up, chemical reactions

20
Enzymes

• Catalyze chemical reactions

21
Enzymes

• Speed-up chemical reactions

22
Protein Monomers/polymers

• Amino acids

• Peptide bond

Peptide bond formation
23
Protein Structure

• 1. Primary

2. Secondary
3. Tertiary
4. Quaternary
24
Nucleic Acids

• Examples DNA, RNA

25
Nucleic Acids

• Function control protein structure, thus
  control cellular function

26
Nucleic Acids Monomers/polymers

• Nucleotides

Three-dimensional double helix
