Abstract:
A natural urease inhibitor is provided to inhibit activity of urease of Helicobacter pylori without side effects, thereby inhibiting colony formation of Helicobacter pylori. A method for inhibiting ammonia formation is also provided to inhibit ammonia formation from the excretions of domestic animals by using the urease inhibitor. A natural inhibitor of Helicobacter pylori urease contains 0.1-5.0 mM of glutathione. A health food for inhibiting Helicobacter pylori urease contains glutathione. The ammonia formation from the excretions of domestic animals is inhibited by spraying the urease inhibitor containing glutathione to the domestic animal excretions.
