The process of chemically digesting protein begins primarily in the stomach. Digestion in mouth begins mostly with the breakdown of polysaccharide called starch to disaccharides called maltose. After the digestive process begins in the mouth with mastication and salivary enzymes, the stomach muscles break down the food into smaller particles for easier mixing with gastric juices. Esophagus, 3. Digestion is the breakdown of large insoluble food molecules into small water-soluble food molecules so that they can be absorbed into the watery blood plasma.In certain organisms, these smaller substances are absorbed through the small intestine into the blood stream.Digestion is a form of catabolism that is often divided into two processes based on how food is broken down: mechanical and . Breaking it down When you begin chewing, glands in your mouth and throat begin to secrete saliva. The diagram of the process of chemical digestion and absorption shows the path that food takes through the digestive system.

This process can start with the sight or smell of food. Chemical digestion is the process of reducing food to a size where the nutrients can be absorbed into the bloodstream. The by-products of this reaction are carbon dioxide and urine. Saliva also has an enzyme that begins to break down starches in your food. In other words, plant enzymes can enhance the digestion of food and the delivery of nutrients to the blood even if you have a compromised digestive system.
