   note: the term sugar includes several commercial grades, as
         the white or refined, granulated, loaf or lump, and the
         raw brown or muscovado. in a more general sense, it
         includes several distinct chemical compounds, as the
         glucoses, or grape sugars including glucose proper,
         dextrose, and levulose, and the sucroses, or true
         sugars as cane sugar. all sugars are carbohydrates.
         see carbohydrate. the glucoses, or grape sugars, are
         ketone alcohols of the formula c6h12o6, and they turn
         the plane of polarization to the right or the left.
         they are produced from the amyloses and sucroses, as by
         the action of heat and acids of ferments, and are
         themselves decomposed by fermentation into alcohol and
         carbon dioxide. the only sugar called acrose as yet
         produced artificially belongs to this class. the
         sucroses, or cane sugars, are doubled glucose
         anhydrides of the formula c12h22o11. they are usually
         not fermentable as such cf. sucrose, and they act
         on polarized light.

   2. by extension, anything resembling sugar in taste or
      appearance; as, sugar of lead lead acetate, a poisonous
      white crystalline substance having a sweet taste.

      acceptable something obnoxious; honeyed or soothing words.
