Are biological macromolecules organic or inorganic compounds?
The definition of "organic" is somewhat vague: it can mean containing carbon, or it can mean coming from living things, particularly as defined by the United States Department of Agriculture. 

To further confuse the issue, some carbon compounds, such as sodium carbonate or tungsten carbide, are sometimes defined as inorganic.

So state a particular definition, and examine those compounds according to that definition.
