Which is the editor doing the same thing less flippantly: "hexuronic acid" is a generic term for an acid produced by partial oxidation of hexose sugars: glucose, for example, would give glucuronic acid, mannose gives mannuronic acid and galactose, galacturonic acid.

I suspect that Szent-Györgi could have got away with ignuronic or godnuronic acid, leaving ignose / godnose as the parent hexose....
