The digestion of proteins starts in the______

The digestion of proteins starts in the stomach. When we eat protein-rich foods such as meat, eggs, or dairy products, the proteins are broken down into smaller units called amino acids. This process of breaking down proteins into smaller units is called digestion. In the stomach, proteins are mixed with gastric juices that contain hydrochloric acid and a digestive enzyme called pepsin. The hydrochloric acid helps to break down the proteins into smaller units, while pepsin cuts the proteins into even smaller pieces. Once the proteins have been broken down into smaller units, they move into the small intestine, where they are further broken down into individual amino acids by digestive enzymes produced by the pancreas and the small intestine. In summary, the digestion of proteins starts in the stomach, where they are broken down into smaller units by the action of gastric juices containing hydrochloric acid and pepsin. The smaller units are then further broken down into individual amino acids in the small intestine.
