Properties of Macromolecules

1
Properties ofMacromolecules

• Carbohydrates, Proteins, Lipids, Nucleotides

2
Lipids

• Trans vs. Cis fatty acids
• Properties of lipids nonpolar, hydrophobic, long
  hydrocarbon chains

3
Nucleic acids

• Basic unit nucleotide

4
Carbohydrate

• Ends with ose
• Carbo carbon
• Hydrate water (2 hydrogen, 1 oxygen)
• Which of the following is not a carbohydrate?
• C6H6 C12H22O11 C5H10O5
• C6H12O6N C2H6O

5
Polymerizing carbohydrates
6
Proteins

• Basic monomer unit amino acid
• Four conformation (folding) levels
• Easily denatured (lose conformation) when pH,
  temperature, etc. change

7
Protein conformation levels
Primary peptide bonds
Tertiary R-group interactions
Secondary hydrogen bonds
8
Protein conformation levels
Quaternary Structure

Enzymes
10
Thermodynamics

• Reactions in living systems cannot proceed
  without energy and enzymes.

Catabolic reaction sucrose hydrolysis

• Benedicts Solution qualitatively determines the
  presence of glucose
