Properties of
Macromolecules
Carbohydrates,
Proteins, Lipids,
Nucleotides
Lipids


Trans vs. Cis fatty
acids
Properties of lipids:
nonpolar, hydrophobic,
long hydrocarbon
chains
Nucleic acids

Basic unit: nucleotide
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

Polymerizing carbohydrates
Proteins

Basic monomer unit: amino acid

Four conformation (folding) levels

Easily denatured (lose conformation)
when pH, temperature, etc. change
Protein conformation levels
Primary:
peptide bonds
Tertiary: Rgroup
interactions
Secondary: hydrogen bonds
Protein conformation levels
Quaternary Structure
Enzymes
Thermodynamics

Reactions in living systems cannot
proceed without energy and enzymes.
How long would this take?
Catabolic reaction: sucrose
hydrolysis

Benedict’s Solution: qualitatively
determines the presence of glucose
