Symptoms of a urinary tract infection (UTI) are similar in men, women, and children. Early symptoms and signs are usually easy to recognize and primarily involve pain, discomfort, or burning when trying to urinate.
Protein digestion begins in the stomach with the action of an enzyme that we previously learned about called pepsin. Pepsin is the active protein-digesting enzyme of the stomach. When pepsin acts on the protein molecule, it breaks the bonds that hold the protein molecule together, called peptide bonds.
Protein digestion occurs mainly in the stomach and also in the small intestine. <br /><br /> When protein food is eaten and enters the stomach, the hydrochloric acid in the stomach denatures the protein. This means it starts to break the protein down into short chains of amino acids joined together (peptide chains).
