Carbon #C#


Life as we know it , is based on more or less complicated carbon-based molecules. we may say that (almost) all 'organic' compounds contain carbon.

On the other hand: not all carbon containing compounds are organic. An example is calcium carbonate #CaCO_3#, also known as calcite, marble o.a., that may have a non-organic origin.
