Although compositions of approximately 25 percent of organic compounds are known, the majority still does not have clear chemical structures or processes, and their control means and technologies are not fully understood as well.

about 25% of the organic matter are known to the specific chemical composition,
Most of the chemical structure and the process remains unclear,
control approaches and technologies are also unclear?
