Thus glucose, fructose, and maltose all reduce Fehling's solution (which contains cupric oxide, Appendix II) with the formation of a red precipitate of cuprous oxide, and are consequentlv known as reducing sugars.

It mav be added that neither inulin nor the dextrins effect reduction of this reagent. For microchemical purposes, especially when but small quan- tities of sugars are present, the foUomng procedure is more advisable. The sections are mounted in a drop of a solution.
