NUTRIENTS (CARBOHYDRATES (made of elements (carbon, hydrogen, oxygen, C6…

- - - - Monosaccharides
        
        cellulose
        
        starch
        
        glycogen
        
        aka singe sugars
      - disaccharides
        
        aka double sugars
        
        maltose
        
        lactose
        
        sucrose
    - - maltose
      - lactose
      - sucrose
      - aka complex carbohydrates
  - - - To test for reducing sugars
        
        reducing sugars: all the Mono and Polysaccharides except sucrose
      - The Benedict's Solution (blue) is added onto the food
        
        if the solution is still blue, reducing sugars are not present
        
        Blue to green
        
        green to yellow / orange
        
        yellow / orange to brick red
    - - add iodine into the food sample
        
        if it remains brown, no starch is present
        
        if it becomes blue black, starch is present
- - - - fatty acid chain is straight
      - eg. butter, cheese, meat, cakes
    - - fatty acid chain has a bent
      - olive oil, soybean, walnuts
  - - - Add ethanol to food in the test tube and shake
        
        if the test tube becomes cloudy, there is fats present. if it does not, there is no fats.
- - - - hydrogen
      - oxygen
      - carbon
      - nitrogen
      - optional: sulfur
      - amino acids are tied by a chain called peptide bonds
        
        called Polypeptide
        
        Polypeptides becomes proteins
  - - - add the biuret solution into the food inside the test tube and shake
        
        if it remains blue, there is no proteins
        
        if it becomes violet, proteins are present
