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)
