*read lab manual and do quiz*
Organic Molecules:
Escherichia coli (E. Coli)
oVery common in lab / environment (largely studied)
oHow much of the cell is water? 70%
o2% carbohydrates
o55% proteins
o24% nucleic acids
o9% lipids
o6% mixed macromolecules
o3% cofactors
o1% inorganic ions:
Organic molecules contain carbon and hydrogen (phospholipid example) and can be natural or synthetic
oSome molecules that contain carbon are NOT organic (CO2) – depending on your point of view, Carbon
Dioxide can be seen as organic or not
Is AZT (synthetic antiviral drug) organic? Yes
Human 18.5% carbon – Earth 0.03% carbon
Life is carbon-based because:
o it has a valence of 4
oCarbon cycle (carbon moving around the earth a lot – in the air, ground, form organism to organism)
oYou can make carbon chains and rings (silicon cannot)
Despite there being more silicon on earth, and it also having a valence of 4, silicon cannot make
chains/rings
Polymers: large organic molecules made when monomers are joined into chains
oDimer – two monomers
oOligomer – between two and ten

Document Summary
70: 2% carbohydrates, 55% proteins, 24% nucleic acids, 9% lipids, 6% mixed macromolecules, 3% cofactors, 1% inorganic ions: Organic molecules contain carbon and hydrogen (phospholipid example) and can be natural or synthetic: some molecules that contain carbon are not organic (co2) depending on your point of view, carbon. Dioxide can be seen as organic or not. Human 18. 5% carbon earth 0. 03% carbon. Life is carbon-based because: it has a valence of 4, carbon cycle (carbon moving around the earth a lot in the air, ground, form organism to organism, you can make carbon chains and rings (silicon cannot) Despite there being more silicon on earth, and it also having a valence of 4, silicon cannot make chains/rings. Polymers: large organic molecules made when monomers are joined into chains: dimer two monomers, oligomer between two and ten. Dehydration reactions occurs during synthesis (it creates water / water leaves the molecule)
