* Total organic carbon, often used as a non-specific indicator of water quality

*** Total synthesis, the complete organic synthesis of complex organic compounds, usually without the aid of biological processes

* Total organic carbon

* Total Kjeldahl Nitrogen or TKN is the sum of organic nitrogen, ammonia ( NH < sub > 3 </ sub >) and ammonium ( NH < sub > 4 </ sub >< sup >+</ sup >) in the chemical analysis of soils.

* Total organic carbon

Total organic carbon ( TOC ) is the amount of carbon bound in an organic compound and is often used as a non-specific indicator of water quality or cleanliness of pharmaceutical manufacturing equipment.

* Total Carbon ( TC ) – all the carbon in the sample, including both inorganic and organic carbon

Total inorganic carbon is not believed to limit primary production in the oceans, so its increasing availability in the ocean does not directly affect production ( the situation on land is different, since enhanced atmospheric levels of CO < sub > 2 </ sub > essentially " fertilize " land plant growth ).

Total emissions from the worldwide 500, 000 km < sup > 2 </ sup > of degraded peatland may exceed 2. 0 Gtons ( including emissions from peat fires ) which is almost 6 % of all global carbon emissions.

In terms of measurement, four basic parameters are of key importance: Total inorganic carbon ( TIC, T < sub > CO2 </ sub > or C < sub > T </ sub >), Total alkalinity ( T < sub > ALK </ sub > or A < sub > T </ sub >), pH, and pCO < sub > 2 </ sub >.

* Total inorganic carbon

Total inorganic carbon is typically measured by the acidification of the sample which drives the equilibria to CO < sub > 2 </ sub >.

* Total Inorganic Carbon ( TIC ) – often referred to as inorganic carbon ( IC ), carbonate, bicarbonate, and dissolved carbon dioxide ( CO < sub > 2 </ sub >).

Many are phototrophic, although some groups contain members that are mixotrophic, deriving energy both from photosynthesis and uptake of organic carbon either by osmotrophy, myzotrophy, or phagotrophy.

In chemistry, an alcohol is an organic compound in which the hydroxyl functional group (- OH ) is bound to a carbon atom.

In organic chemistry, compounds composed of carbon and hydrogen are divided into two classes: aromatic compounds, which contain benzene or similar rings of atoms, and aliphatic compounds (; G. aleiphar, fat, oil ), which do not contain those rings.

Bromine is slightly soluble in water, but it is highly soluble in organic solvents such as carbon disulfide, carbon tetrachloride, aliphatic alcohols, and acetic acid.

The largest sources of inorganic carbon are limestones, dolomites and carbon dioxide, but significant quantities occur in organic deposits of coal, peat, oil and methane clathrates.

In these examples, the harmful effects may result from contamination of the carbon particles, with organic chemicals or heavy metals for example, rather than from the carbon itself.

In organic chemistry a carbonate can also refer to a functional group within a larger molecule that contains a carbon atom bound to three oxygen atoms, one of which is double bonded.

A carbohydrate is an organic compound that consists only of carbon, hydrogen, and oxygen, usually with a hydrogen: oxygen atom ratio of 2: 1 ( as in water ); in other words, with the empirical formula.

With the proper mixture of water, oxygen, carbon, and nitrogen, micro-organisms are allowed to break down organic matter to produce compost.

More recalcitrant organic carbon polymers such as cellulose, hemi-cellulose, lignin, aliphatic compounds, waxes and terpenoids are collectively retained as humus.

Much organic carbon retained in many agricultural areas worldwide has been severely depleted due to intensive farming practices.

Forest fires release absorbed carbon back into the atmosphere, as does deforestation due to rapidly increased oxidation of soil organic matter.

This role as a sink for CO < sub > 2 </ sub > is driven by two processes, the solubility pump and the biological pump .< ref > The former is primarily a function of differential CO < sub > 2 </ sub > solubility in seawater and the thermohaline circulation, while the latter is the sum of a series of biological processes that transport carbon ( in organic and inorganic forms ) from the surface euphotic zone to the ocean's interior.

A small fraction of the organic carbon transported by the biological pump to the seafloor is buried in anoxic conditions under sediments and ultimately forms fossil fuels such as oil and natural gas.

In Canada's boreal forests as much as 80 % of the total carbon is stored in the soils as dead organic matter.

In organic chemistry, in addition to oxidation, reduction or acid-base reactions, a number of other reactions can take place which involve covalent bonds between carbon atoms or carbon and heteroatoms ( such as oxygen, nitrogen, halogens, etc .).

Chloroplasts capture light energy, store it in the energy storage molecules ATP and NADPH and use it in the process called photosynthesis to make organic molecules and free oxygen from carbon dioxide and water.

Through catabolism of sugars, fats, and proteins, a two carbon organic product acetate in the form of acetyl-CoA is produced.

An organic compound is defined as any compound based on a carbon skeleton.

In organic chemistry a diene ( ) or diolefin ( ) is a hydrocarbon that contains two carbon double bonds.

By breaking down dead organic matter, decomposers release carbon back to the atmosphere and facilitate nutrient cycling by converting nutrients stored in dead biomass back to a form that can be readily used by plants and other microbes.
