1_3.1 Carbohydrates

1. Monomers

   • Basic, Individual chains that make up long chains
     • Polymers
   • Animo Acids
   • Monosaccharides
   • Nucleotides

2. Contains 3 elements

   • Carbon
   • Oxygen
   • Hydrogen

3. Monosaccharides

   • Sugar
   • Sweet, Soluble
   • (CH2O)n
     • N=3-7
   • Examples
     • Glucose+Glucose=Maltose
     • Glucose+Fructose=Sucrose
     • Glucose+Galatcose=Lactose

4. Reducing Sugars

   • All mono and some disaccharides are reducing Eg Maltose
   • Benedict's Test
     • Heat Benedict's Solution to a test sample in a water bath for 5 mins
       • If present then red precipitate formed
     • Filter solution and weigh precipitate or remove precipitate and use a colorimeter to measure absorbance of BR
