N-十八烷酰基-L-高丝氨酸内酯，有时也称为C18-HSL，是一种N-酰化的高丝氨酸内酯（AHL）。AHL的酰基长度（C4-C18），C3的取代（氢，羟基或氧代基）以及脂肪酸链中是否存在一个或多个碳-碳双键的情况都不同。这些差异通过LuxR家族的转录调节子的亲和力赋予信号特异性。N-十八烷酰基-L-高丝氨酸内酯是由LuxI AHL合酶同系物SinI产生的四个亲脂性，长酰基侧链的AHLs之一，参与了Sinorhizobium meliloti |菌株的群体感应信号传递。这种和其他疏水性AHL倾向于位于细菌的
N-octadecanoyl-L-Homoserine lactone, sometimes called C18-HSL, is an N-acylated homoserine lactone (AHL). AHLs vary in acyl group length (C4-C18), in the substitution of C3 (hydrogen, hydroxyl, or oxo group), and in the presence or absence of one or more carbon-carbon double bonds in the fatty acid chain. These differences confer signal specificity through the affinity of transcriptional regulators of the LuxR family. N-octadecanoyl-L-Homoserine lactone is one of four lipophilic, long acyl side-chain bearing AHLs produced by the LuxI AHL synthase homolog SinI involved in quorum-sensing signaling in strains of|Sinorhizobium meliloti|. This and other hydrophobic AHLs tend to localize in relatively lipophilic cellular environments of bacteria and cannot diffuse freely through the cell membrane. The long-chain N-acylhomoserine lactones may be exported from cells by efflux pumps or may be transported between communicating cells by way of extracellular outer membrane vesicles.
