      - Sulfur
      - Phosphorus
    - - Meats, Fish, Milk, Nuts and Eggs
    - - Enzymes speed up the rate of chemical digestion
        
        Enzymes help to digest things like starch into maltose, proteins into amino acids, fats into glycerol + fatty acids.
      - Enzyme acts on substrate
        
        Enzymes remain unchanged after the digestion of food is completed.

        action of the teeth
        
        Food is chewed with the help of teeth to cut and grind them into smaller pieces.
        
        This increase their surface area and allows enzymes to digest them faster.
      - Chemical
        
        salivary amylase
        
        Starch is digested into maltose by salivary amylase
  - - - Food stays in the stomach for about 2 to 6 hours. The partly digested food is called chyme
    - - Two type of digestion take place
        
        Chemical digestion
        
        Proteins are digested into amino acids by proteases.
        
        Physical digestion
        
        The churning action by the muscular wall of the stomach causes food to break up further into smaller pieces. It also helps food mix with gastric juice
      - juices and acids
        
        Gastric juices
        
        contains water, hydrochloric acid and proteases.
        
        Hydrochloric acid has two important functions
        
        Kill bacteria in food
        
        provide acidic environment for proteases to work effectively
  - - - The liver, the gall bladder and the pancreas are the organs that associate with the small intestine.
    - - Physical digestion through emulsification
        
        Bile is produced by the liver and stored in the gall bladder. It is released into small intestine when fats reach the region. Bile is not an enzyme. It is a substance to break up fat molecules into fat globules. This process is called the emulsification. Emulsification increases the surface area of the fat molecules so that they can be digested by lipase faster.
      - The pancreas secretes pancreatic juice and the small intestine secretes intestinal juice. These juices contain various enzymes such as amylase, maltase, carbohydrase, proteases and lipase. Starch are digested by amylase into maltose. Maltose are digested by maltase into glucose. Carbohydrates are digested by carbohydrates into glucose. Proteins are digested by proteases into amino acids. Fats are digested by lipase to fatty acids and glycerol.
