The CHo chain is the chain of life

The CHo chain is the chain is the chain of life, comprising of carbon hydrogen and oxygen. The most import thing  in this chain is carbon, without carbon life is absent. Carbon is the blackest substance on earth, the concentration of carbon is the reason for the colour of your skin, some argue that melanin is the reason for the colour if you skin and supporters or melanin say that is produced in the central nervous system however the central nervous system is not a producer but  merely as conduit that helps to help electrons travel and not produce so supporters of melanin arguments are inconsistent.
