Life on earth is generally described as carbon-based
because of the prominence of carbon in biomolecules. The earths
carbon cycle is highly complex and is the subject of increasing
scrutiny due to concerns about global warming. Green plants,
algae, and some prokaryotes fix atmospheric carbon dioxide to generate
hundreds of thousands, perhaps millions, of organic molecules. These biologically synthesized organic structures
serve as substrates for the broad set of enzymes produced
by microbes that are found in terrestrial and aquatic environments.
Some of these enzymes can also use chemically synthesized organic compounds as substrates.
Most compounds in the UM-BBD contain carbon.
