Lysylphosphatidylglycerol [42241-11-2]

Lysylphosphatidylglycerol (Lys-PG) is a major cationic phospholipid in the membrane of Staphylococcus aureus. Its positively charged lysine moiety provides resistance to host cationic antimicrobial peptides like defensins. This molecule is a key reagent for studying bacterial membrane biology, host-pathogen interactions, and mechanisms of antimicrobial resistance in both in vitro and in vivo research models.
