The class of biological molecule that contains fatty acids is lipids.
Proteins are probably the largest class of biological molecules that always contain nitrogen.
Lipids, or fatty acids, are a class of organic compounds found in the body. They're used as energy storage, but are also found in the membrane of all eukaryotic cells.
In short, no. Amino Acids are made up of molecules. Groups of amino acids form proteins. DNA is made up of nucleotides. (Similarly to Amino Acids, nucleotides are made up of molecules.)
Heteroaromatic molecules are a class of compounds, not a single identifiable compound.
There are many. Aldehydes, ketones, carboxylic acids, amides, esters, acid anhydrides and organo-metallic compounds such as Iron Pentacarbonyl etc contain the -C=O group.

The many ways that monomers of each class of biological molecule can be combined into polymers
DOT hazard Class 8 contains corrosive materials such as acids and bases.
The carbonyl group exist in ketones, aldehydes, esters etc.
sugar
These compounds are called amines.
