Considering there are estimated to be on the order 10^60 "small" organic molecules (molecular weight of under 500g/mol) that are stable under some "reasonable" conditions [0], even that may be a pretty big understatement. Just consider all of the combinations of polymers possible from those molecules. For reference: ~10^80 particles in the observed universe.
And that's ignoring proteins (average molecular weight ~40000g/mol) and many bio-material applications. A strand of DNA has 4^Length permutations.
