When you are eating, there is chemistry involved in the digestion of your food. The breakdown of food is known as chemical digestion.
Chemical digestion uses enzymes such as Amylase, Protease and Lipase to break down different components of food, such as proteins, carbs and fats. The enzymes break the chemical bonds that hold the food particles together.
Amylase breaks down starches and carbs into sugars. Protease breaks down proteins into amino acids. Lipase breaks down oils into glycerol and fatty acids.
Since, the food particles break apart into small digestible pieces of food. Inside of your body the food is moving in your intestine. When the particles are moving it allows the food particles to be exposed to more digestive enzymes. The movement of the food also helps the food to proceed towards the large intestine.
Without chemical digestion, our bodies won’t be able to absorb nutrients, leading to health problems and malnutrition.
