Lipopeptides is a research concept centered on a diverse class of amphiphilic molecules comprising a peptide sequence covalently linked to a lipid moiety. This field investigates their unique physicochemical properties, such as membrane interaction and surfactant activity, their broad spectrum of biological functions including antimicrobial and immunomodulatory effects, and their potential applications in areas ranging from therapeutics and drug delivery to industrial processes and environmental remediation, often exploring their microbial biosynthesis and structure-activity relationships.
