Digestion is a necessary part of the absorption process. Food first enters the stomach after you chew and swallow it. The stomach stores the food and liquid you swallow and mixes it with digestive juices that the stomach makes.
The enzymes that are secreted in the stomach are called gastric enzymes. The stomach plays a major role in digestion, both in a mechanical sense by mixing and crushing the food, and also in an enzymatic sense, by digesting it. Pepsin breaks down the protein in the food into smaller particles, such as peptide fragments and amino acids. 2  Protein digestion, therefore, first starts in the stomach, unlike carbohydrate and lipids, which start their digestion in the mouth.
