This is a long thread, and I may have missed something, but some
thoughts...

1. Why not use ordinary sucrose? If your main concern with fructose is
the corn issue, then sucrose -- ordinary table sugar -- should be ok.

2. If you really want something extra-pure, why not get some
pharmaceutical grade glucose (dextrose). Ask your pharmacist. (If you
have connections with someone who works in biological research, you
might check with them, too.)
