What it is
Table sugar with its glucose-fructose bond rearranged so the body takes it apart slowly — sold to sports and clinical nutrition as "sustained energy."
Why your biology objects
Fully digested, no fermentation, but the α-1,6 linkage resists sucrase, so it releases its sugar 4–5× slower — glycemic index ~32 versus sucrose's 67. It still yields free fructose, but at sucrose's escorted 1:1 ratio, so no hepatic-spillover problem. Among the more defensible refined sugars here.
