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 is found in meat, eggs, dairy products and beans, and is used by the body to build muscle and organs. Protein molecules are quite large. Chewing helps break proteins down into smaller particles for digestion. Chemical protein digestion starts in the stomach, where enzymes start to soften the protein molecules. A number of enzymes, including substances from the pancreas, then break down protein into its component amino acids in the small intestine.
