乙酰基-L-高丝氨酸内酯是细菌生物膜中细胞间相互作用的极性介质。酰基高丝氨酸内酯已在数百种细菌中被检测到，高丝氨酸内酯是细胞通讯和调控的主要化学调节剂。乙酰基-L-高丝氨酸内酯可作为群体感应事件的极性阴性对照。 Acetyl-L-homoserine lactone is a polar mediator of cell-to-cell interactions in bacterial biofilms. Acylhomoserine lactones have been detected in hundreds of bacterial species and the homoserine lactones are the major chemical modulators of, within, and between cell communication and regulation. Acetyl-L-homoserine lactone may serve as a polar negative control for quorum sensing events.
