2
What to include in your notes

• In chart format Columns
• Name of macromolecule
• Name of Building Block/ Monomer
• Structure of building block
• Example

• Where produced in the cell

3
Proteins
Amino Acids building blocks (20)
4
(No Transcript)
5

• 4 levels of structure
• Sequence of Amino Acids
• H-bond interactions- Alpha helix and Beta pleated
  sheet
• 3-D structure H- Bond, other interactions
• Several 3-D Proteins combining to form a more
  complex molecule

3D 4D
7
Examples Meat, Beans, Salivary enzymes
Uses Enzymes, Structure (muscle)
Enzymes catalyst Make a reaction go faster
Where produced in cell Ribosomes (Rough ER for
export)
8
Carbohydrates
(CH2O)X
Simple sugars/ Monosaccharide Building blocks

Complex Carbohydrates
Disaccharides
Starches Polysaccharides
Ends in -saccharide
Examples Sugar (mono/di) Starch (poly)
Uses Short term energy Plants Long term
energy Storage (Starch)
Where produced in cell Chloroplast
(photsynthesis)

connector and 3.nitrogen base
Building blocks- Nucleotides
14
Examples DNA, RNA, ATP Energy Molecule of the
body
Money
Uses Genetic information (DNA), Carries
messages (RNA), Energy molecule (ATP)
Where produced in cell Nucleus (DNA RNA) During
respiration (ATP)
