MICRONUTRIENTS   2 
  Vitamins are nutritionally important organic 
         compounds. 
   Often coenzymes or cofactors for enzyme function.
   Vitamins form biochemically through the life 
  processes of the plants and animals we eat.     
    Plants and animals synthesize vitamins.
       Originally it was thought these necessary 
 compounds were all amines. Since they were vital 
   
          to our health they became known as              
   
              “vital amines”, ie. vitamines. 
     When it was discovered that some were not 
 amines, ie. not ' --ines',  the name was changed to 
                                vitamins.
