The number of organic compoundsfarexceeds that ofinorganic compounds, but very few other elements are involved along with the ubiquitous carbon.Most of them are other nonmetals, most commonly carbon (C) and hydrogen (H), which are always present; oxygen (O), nitrogen (N), sulfur (S) and ...
All organic compounds contain carbon, and organic chemicals are the basic chemicals found in all living things. Many organic compounds in our air today do not occur naturally, but are instead human-made, formed during industrial processes or combustion. VOCs include a variety of chemicals, some ...

Then, organisms turn to other compounds as oxidants of organic carbon in order of redox potential (see Fig. 12.5). The most efficient process is not always used (e.g., a bacterium that can only use nitrate to oxidize organic carbon may continue to do so even in the presence of O2). ...
