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.
It also converts the inactive enzyme, pepsinogen, into it's active form, pepsin. Which is protein digesting enzyme. Although pepsin is itself a protein, the acid in the stomach does not denature it because it has evolved to work optimally in the acidic environment. î î î proteases role in protein digestion the enzymes that digest polypeptides are called proteases.
