Chemistry of Life

Chemical reactions occur under the right conditions of temperature and pressure and with the proper catalyst. a catalyst can greatly increase the:
-Trace elements (less than 0.01%)
-Nitrogen (3.3%)
-Hydrogen (9.5%))
-Carbon (918.5%)
-Oxygen (65%)

Organic Macromolecules
-Carbohydrates
-Lipids
-Proteins
-Nucleic Acids

Synthesis Reaction
A+B ----> AB

Reactants A and B combine chemically to form a more complex molecule.
