As noted above, sugars may be classified as reducing or non-reducing based on their reactivity with Tollens', Benedict's or Fehling's reagents. If a sugar is oxidized by these reagents it is called reducing, since the oxidant (Ag (+) or Cu (+2)) is reduced in the reaction, as evidenced by formation of a silver mirror or precipitation of cuprous oxide. sims 4 angels cc https://baileylicensing.com
