PQQ is a redox cofactor that plays a crucial role in the function of several enzymes involved in energy metabolism. It is also known for its powerful antioxidant properties, which help in neutralizing free radicals - unstable molecules that can cause cellular damage. The body's ability to manage oxidative stress is particularly vital during viral infections, including COVID-19, where the immune response generates a significant amount of reactive oxygen species (ROS).
Water treatment chemicals are a diverse group of substances designed to enhance the quality of water. They are used in various processes, including coagulation, flocculation, disinfection, and corrosion control. Commonly supplied chemicals include chlorine, alum, polymer, and sodium hypochlorite, each fulfilling specific functions in the treatment process. The selection of appropriate chemicals depends on various factors, including the type of contaminants present in the water, regulatory standards, and the intended use of the treated water.
