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).
Chemical digestion that occurs in the stomach is mainly via enzymes and hydrochloric acid. The stomach secretes pepsinogen which turns into pepsin and breaks down proteins.The hydrochloric acid provides a low pH level in which the enzymes can thrive.hemical digestion is the breaking down of food particles through chemical reactions. Chemical and mechanical digestion combine to process food, absorbing nutrients and minerals and discarding the waste. Very little mechanical digestion occurs outside of the mouth.
