1. MACROMOLECULES Bigger still Organic More complex C, H, O, N atoms
CELLULOSE
polypeptide polysaccharide

2. carbohydrates
nucleic acids
proteins
See any
patterns?
lipids

3. • Macromolecules are made by linking
together repeated smaller molecules
each link = monomer
chain = polymer
Each link is a monomer
The chain is a polymer
Gr: mono- one; poly- many

4. Ex: chains of simple sugars like glucose
create complex carbohydrates like starch
monomer : glucose
polymer : starch

5. Building polymers is a dehydration synthesis reaction
Creating a
disaccharide
What are the
functional
groups?
Water!
Water!
Peptide bonding of amino acids

6. Breaking the bonds of a polymer requires water (hydrolysis!)

7. Building a macromolecule is a hierarchy: CHNOPS Carbon (4 bonds)
add H (organic Hydrocarbon)
add Functional Group(s) (hydrophyllic building block)
Monomer* (some are isomers)
Dehydration rxn (between monomers)
Polymer**
*glucose, animo acid, nucleotide…
**Carbohydrate, Protein, Nucleic Acid, Lipid^
^2+ subunits, not a monomer
