It doesn't bypass anything. For one thing, F6P is the rate-limiter. It's irrelevant anyway, since both glucose and fructose (and other monosaccharides) can be converted into F6P and eventually into F1,6BP. And then all of this is even more irrelevant, since dpggmm and you are referring to fructose
glycogenesis, and the reaction you're referencing here is
glycolysis, its exact opposite.

'Good' and 'bad' in which way? From what perspective? For what person? To what effect? As a general rule it's atrocious and misleading.
