Presentation Transcript
results which of the solutions reacted to benedict s solution
Results: Which of the solutions reacted to Benedict’s Solution?
  • Monosaccharide-Known
  • Honey
  • Apple Juice
  • Milk (in some classes)
results which of the solutions reacted to iodine solution
Results: Which of the solutions reacted to Iodine Solution?
  • Polysaccharides
  • Oat Water
  • Rice Water
  • Milk (a little bit)
conclusion a mono di or polysaccharides
Conclusion:(a) Mono, Di or Polysaccharides?
  • Reaction with Benedict’s Monosaccharides Present
  • Benedict’s only reacts with Monosaccharides
  • Honey, Apple Juice and Milk contains monosaccharides
  • You saw a orange-yellow-brown color change, resulting from Benedict’s solution!
conclusion b structure of molecules benedict s
Conclusion:(b) Structure of Molecules & Benedict‘s
  • Reacted w/Benedict’s  Monosaccharide
  • Monosaccharide = 1 sugar
  • Structure of Honey, Apple Juice & Milk:
    • The carbohydrate was made of individual, single sugar units.
    • Most likely glucose or fructose.
conclusion c mono di or polysaccharides
Conclusion:(c) Mono, Di, or Polysaccharides?
  • Reaction with Iodine Polysaccharides Present
  • Iodine only reacts with Polysaccharides
  • Oat Water, Rice Water & Milk contains polysaccharides
  • You saw a blue-black color change, resulting from Iodine reaction!
conclusion d structure of molecules iodine
Conclusion:(d) Structure of Molecules & Iodine
  • Reacted w/Iodine  Polysaccharides
  • Polysaccharide = Many Sugars
  • Structure of Oat Water, Rice Water & Milk:
    • The carbohydrates were large molecules, made of repeating sugar units.
    • Most likely starchy.
conclusion e mono di polysaccharides
Conclusion:(e) Mono, Di, Polysaccharides?
  • No Reaction  Disaccharide
  • No Color Change Ever  Disaccharide
  • Sugar Water must contain disaccharides
conclusion f structure of molecules nada
Conclusion:(f) Structure of Molecules & Nada
  • No Reaction  Disaccharides
  • Disaccharide = 2 or Double Sugar
  • Structure of Sugar Water:
    • Made of double sugar units
    • Most likely sucrose or sucralose
conclusion g solutions long energy
Conclusion:(g) Solutions & Long Energy
  • Oat Water & Rice Water:
    • Largest Carbohydrates
    • Most Bonds  Most Energy over Long Period
conclusion h solutions quick energy
Conclusion:(h) Solutions & Quick Energy
  • Honey & Apple Juice:
    • Small Carbohydrates
    • Few Bonds  Little Energy over Short Period
