Polylysine Hydrochloride
Also known as: ε-Polylysine, ε-PL, ε-poly-L-lysine, ε-PLH, ε-Polylysine Hydrochloride
Overview
ε-Polylysine hydrochloride (ε-PLH) is a natural antimicrobial peptide that acts as a hydrochloride salt of ε-poly-L-lysine, a biopolymer synthesized by the bacterium *Streptomyces albulus*. Known for its potent antimicrobial properties, ε-PLH is primarily employed as a preservative in food and pharmaceuticals. Characterized by its effectiveness against a diverse range of microorganisms, particularly bacteria and fungi, it has gained attention for enhancing the quality of food products and supporting animal health in husbandry. Although moderate in research maturity, ongoing studies are focused on its biomanufacturing processes and increasing applications. However, evidence supporting its efficacy in humans remains limited, highlighting a need for further clinical investigation.
Benefits
Research indicates that dietary supplementation of ε-PLH can significantly boost egg quality and production in poultry, with reports of increased egg weight and lower breakage rates in laying hens. The strength of this evidence primarily stems from animal studies, particularly in the poultry sector. Additionally, ε-PLH has been linked to improved growth performance and health in livestock, though specific effect sizes and clinical relevance for human applications remain unestablished. The positive impacts on animal health are noted to surface over multiple weeks of supplementation, emphasizing the need for extended trials to better understand long-term benefits.
How it works
ε-Polylysine hydrochloride exerts its antimicrobial effects primarily by disrupting the integrity of bacterial cell membranes, which leads to cell lysis and subsequent death. The compound interacts with the gastrointestinal system when consumed, affecting microbial populations. Studies have identified bacterial cell membranes as key molecular targets, though detailed data on human absorption and bioavailability is still sparse. The mechanism underscores its potential effectiveness as a preservative and therapeutic agent.
Side effects
The safety profile of ε-PLH suggests it is generally regarded as safe, particularly in food and animal feed applications. Documented side effects in human studies are minimal; however, gastrointestinal disturbances are a potential concern, reported in less than 5% of cases. Rare side effects (<1%) have not been established. Importantly, no significant drug interactions have been noted, nor have any contraindications been reported. There is a lack of comprehensive safety data regarding special populations, particularly pregnant or lactating women, necessitating cautious consideration in these groups until further research clarifies any potential risks.
Dosage
No recommended dosing parameters for ε-PLH have been established for human use, as most knowledge derives from animal studies. In these studies, dosages around 0.05% of the diet were effective, suggesting a similar proportion could be considered in specific formulations. Optimal timing for supplementation appears to be continuous to achieve desired benefits. As ε-PLH is administered as a hydrochloride salt, factors related to its absorption in humans remain under-explored, and no defined upper safety limits or thresholds have been established.
