      What is the process called while sucrose is being produced.. if there is one.

      I have a paper due and the question is
      Tablesugar what is it made of? Explain it & Give the molecular formula.

      I know the formula is
      C6h12o6 + C6h12o6 = C12H22o11 + h2o
      (Glucose) (glucose) = (sucrose) (water)

      but i think i remeber my lab instuctor calling it something.. please help!!

      thanks

      what about kondensation?
      BTW all the letters should be capital! 😉

      I think you will find that sucrose (C12H22O11)is made of glucose and fructose.

      Glusose + glucose produces Maltose.

      The formation of sucrose or any disacharide from it’s complonents is a "condensation" reaction – (water is produced).

      The process is called condensation, although chemists sometimes refer to it as dehydration synthesis.


      @Dougalbod

      Glucose+glucose can produce one of probably something like a dozen different disaccharides. When the bond is 1->4, it is maltose, when the bond is 1->1 it is trehalose tc.

      quote MrMistery:

      The process is called condensation, although chemists sometimes refer to it as dehydration synthesis.

      I think, that dehydration is called only, when the water comes from one molecule, not if are two molecules joined and water produced. In that case it’s condensation 😉

      you know i think technically you are correct. however, for some reason people DO call it "dehydration synthesis" (I have never heard it being referred to simply as dehydration). Perhaps it is some kind of artifact from long ago when that wasn’t the rule.
      Anyway, I prefer cndensation anyway, but the term dehydration synthesis is very much in common use (a google search will convince you of that if you don’t believe me)

      OK, I don’t say, I don’t belive you. I have just never heard it before 🙂

      It is done through the dehydration reaction in which the hydrogen from one sugar binds with the hydroxyl group of another to form water, creating a glycosidic bond.

      Don’t say!
