i think that
Pentanal;
Pentan-2-on;
Pentan-3-on;
2,3Dimethylpropanon;
2-Methylbutanon;
2-Ethylpropanal;
2-Methylbutanal;
3-Methylbutanal;
3-Methylbutanon;
is the right answer,but there are even more
A ribosome is the organelle that builds proteins. Is that what you are looking for? If not, sorry! :(

All gymnosperms have cones as reproductive structures.
The International Union of Pure and Applied Chemistry (IUPAC) was founded in 1919 by chemists from industry and academia. It was established to advance the worldwide understanding and application of chemistry and to standardize the naming and notation of chemical compounds.
ribosome
The term is called the "resonance hybrid." It represents the actual electronic structure of a molecule that is a blend of all the possible resonance structures.

There is -to my knowledge- no chemical compound named either 'patton' or 'reeder'. 'Patton' and 'Reeder' are common names of persons and towns all over the world, those are not having IUPAC-names becuase they're not chemicals.
Ribosomes are the building structures in all cells.

They may be ethene, propene! ethyne, propyne and all the unsaturated hydrocarbons
Ribosomes are the protein-building structures contained in all cells.Ribosomes
Probably you think at chemical elements; we know today 117 elements (112 elements were homologated now by IUPAC).

Yes, all natural languages have heads in their syntactic structures.
All buildings are structures but not all structures are buildings
