What is the largest, non-reduce-able, molecule known? I specify non-reduce-able not to imply cannot be broken down in a redox reaction, but rather, to specify that it is only that molecule so long as it exists in that state. For example, DNA does not count because it can be broken into a smaller strand and still be considered DNA. I want the single largest molecule we know of that exists as such and only as such.

The line between monomer, oligomer, and polymer is often not very tightly defined, so I'm not sure a rigorous answer is possible.
