Concern about the scarcity of the particular species of coral and its possible overexploitation has prompted scientists to produce the compound by synthetic means.

And that is a circumstance that could supply the chemical energy and the chemical compounds needed to sustain life.

All the energy to support these life forms is coming from inside the Earth so, chemosynthesis.

Synthetic biologists are manipulating it.

The European Trade Union Confederation (ETUC) is participating in the chemical substance policy review of the European Union Commission with the goal of a comprehensive system for the registration, evaluation and authorization of chemicals.

The International Union of Biochemistry and Molecular Biology (IUBMB), has statutes which specify its mission as to foster and support the growth and advancement of biochemistry and molecular biology as the foundation from which the biomolecular sciences derive their basic ideas and techniques in the service of mankind.

With a refractometer the refractive index of optical media is determined. If the refractive index of a chemical is known it can be used after a synthesis to determine the sample's purity or to audit the synthesis' success.

There are thousands of professionally delimited subjects sprinkled through physics and chemistry to biology and medicine.

Living organisms are created by chemistry.

The following main chemicals are restricted arsenic and arsenic compounds, benzine, cadmium, formaldehyde, lead, mercury, nickel, organic tin, PCB, pentachlorophenol, PCT, ozone depleting substances and a wide range of specific chemicals in cosmetics.

And that's a plastic polymer.
