  2. Total inorganic carbon - Wikipedia

    en.wikipedia.org/wiki/Total_inorganic_carbon

    Total inorganic carbon (C T or TIC) is the sum of the inorganic carbon species. Carbon compounds can be distinguished as either organic or inorganic, and dissolved or particulate, depending on their composition. Organic carbon forms the backbone of key components of organic compounds such as proteins, lipids, carbohydrates, and nucleic acids.

  3. Organic compound - Wikipedia

    en.wikipedia.org/wiki/Organic_compound

    For example, carbon-containing compounds such as alkanes (e.g. methane CH 4) and its derivatives are universally considered organic, but many others are sometimes considered inorganic, such as halides of carbon without carbon-hydrogen and carbon-carbon bonds (e.g. carbon tetrachloride CCl 4), and certain compounds of carbon with nitrogen and ...

  4. Soil carbon - Wikipedia

    en.wikipedia.org/wiki/Soil_carbon

    Soil carbon is present in two forms: inorganic and organic. Soil inorganic carbon consists of mineral forms of carbon, either from weathering of parent material, or from reaction of soil minerals with atmospheric CO 2. Carbonate minerals are the dominant form of soil carbon in desert climates. Soil organic carbon is present as soil organic matter.

  5. Dissolved organic carbon - Wikipedia

    en.wikipedia.org/wiki/Dissolved_organic_carbon

    Aquatic carbon occurs in different forms. Firstly, a division is made between organic and inorganic carbon. Organic carbon is a mixture of organic compounds originating from detritus or primary producers. It can be divided into POC (particulate organic carbon; particles > 0.45 μm) and DOC (dissolved organic carbon; particles < 0.45 μm). DOC ...

  6. Carbon compounds - Wikipedia

    en.wikipedia.org/wiki/Carbon_compounds

    Organic carbon compounds are far more numerous than inorganic carbon compounds. In general bonds of carbon with other elements are covalent bonds. Carbon is tetravalent but carbon free radicals and carbenes occur as short-lived intermediates. Ions of carbon are carbocations and carbanions are also short-lived.

  7. Carbon-based life - Wikipedia

    en.wikipedia.org/wiki/Carbon-based_life

    The enormous diversity of carbon compounds, known as organic compounds, has led to a distinction between them and the inorganic compounds that do not contain carbon. The branch of chemistry that studies organic compounds is known as organic chemistry .

  8. Dissolved inorganic carbon - Wikipedia

    en.wikipedia.org/wiki/Dissolved_inorganic_carbon

    Dissolved inorganic carbon is a key component of the biological pump, which is defined as the amount of biologically produced organic carbon flux from the upper ocean to the deep ocean. [6] Dissolved inorganic carbon in the form of carbon dioxide is fixed into organic carbon through photosynthesis.

  9. Inorganic compound - Wikipedia

    en.wikipedia.org/wiki/Inorganic_compound

    An inorganic compound is typically a chemical compound that lacks carbon–hydrogen bondsā  ‍ — ‍ that is, a compound that is not an organic compound. [ 1 ] [ 2 ] The study of inorganic compounds is a subfield of chemistry known as inorganic chemistry .
