Are there any complex molecules that are not biomolecules and don't get "involved" with organisms and life building?
Buckyballs are naturally occurring. I believe that other graphite forms are too, though I don't keep track of this.Thanks! What about naturally occurring molecules? Did they basically always find their way to integrate into life?
Or could there be some molecule out there that "stays away from life" or if it finds itself inside of living organisms, it doesn't really do anything?
https://en.wikipedia.org/wiki/Miller–Urey_experimentThe Miller Urey Experiment. In the 1950's, biochemists Stanley Miller and Harold
Urey, conducted an experiment which demonstrated that several organic compounds
could be formed spontaneously by simulating the conditions of Earth's early
After Miller's death in 2007, scientists examining sealed vials preserved from
the original experiments were able to show that there were actually well over 20
different amino acids produced in Miller's original experiments. That is
considerably more than what Miller originally reported, and more than the 20
that naturally occur in life [see chart on this page]
Carbon can be organic such as in alkanes or inorganic, as in CO, CO2 CO3-2, and HCO3-. Graphite, soot, buckyballs, fullerenes and diamond are all also inorganic. While inorganic carbon interacts with living systems, they are not necessarily "life" molecules. Even organic carbon compounds do not participate in life chemistry. For example, polyethylene glycol, oligomeric and polymeric alkanes.Almost all naturally occurring complex molecules come from life (though this may differ in how you define a complex molecule). Cabon nanotubes and fullerenes can form in soot from fire, and these don't really do anything inside living organisms.
Kerogen is an example of a geopolymer that is derived from organic detritus under high temps and pressures. During breakdown of the source rock, complex organic molecules are formed such as higher branched and linear alkanes, polycondensed aromatic hydrocarbons, and porphyrins. Porphyrins are derived from chlorophyll in the sediments, and are present in crude oil as erythroetioporphyrins. While derived from life molecules, these porphyrins do not participate in life chemistry.I am aware that carbon is everywhere and CHNOPS basically constitute life. I was just not sure if there was some "subgroup" of "complex molecules" somewhere on earth that naturally form in nature, independent of life.
Thanks for responses everyone, super enlightening!
