What compound is most efficient in bacterial killing by neutrophils?

Hypochlorite is a potent antibacterial agent produced by neutrophils during the respiratory burst, a critical response when bacteria invade the body. Neutrophils, as part of the innate immune response, utilize a variety of mechanisms to eliminate pathogens, and one of the most effective is the generation of reactive oxygen species. Hypochlorite, specifically sodium hypochlorite, is generated from hydrogen peroxide in the presence of myeloperoxidase, an enzyme found in neutrophil granules.

Once formed, hypochlorite works by directly damaging the cell walls of bacteria, as well as interfering with their metabolic processes, leading to cell death. Its high reactivity allows it to rapidly act on various bacterial components, making it one of the most efficient compounds for bacterial killing in the context of neutrophils.

While other compounds such as lysozyme, lactoferrin, and bactericidal permeability increasing protein also play significant roles in the antibacterial activity of neutrophils, they do not exhibit the same potency as hypochlorite. Lysozyme, for instance, hydrolyzes certain bonds in bacterial cell walls but is less effective against all types of bacteria. Lactoferrin has antibacterial properties through its ability
