Confidence votes 106. Protein digestion in humans begins in the stomach. The enzyme pepsin is activated from its' inactive form pepsinogen due to the acidic conditions of the stomach. Pepsin starts digestion of proteins by breaking down the many of polypeptides into shorter peptides. However, complete chemical digestion will not occur until proteins reach the duodenum and the jejunum of the small intestine. Here more enzymes come into play (proteases and peptidases) so that the protein is completely broken down into its' smallest building blocks (the monomers called amino acids).
Carbohydrates. Carbohydrates are your body's preferred energy source and are found in the forms of starch, sugar and fiber. Digestion begins in your mouth where the process of chewing mechanically breaks food into small pieces. Enzymes in the saliva initiate chemical digestion.rotein is found in meat, eggs, dairy products, fish, nuts and beans. Before your body can use protein to build and repair tissues, the large molecules of protein must be digested by enzymes into small molecules called amino acids. Digestion of protein begins in your stomach with the aid of gastric juices.
