一般說明
胆汁盐是一种有机钠盐，包含任何胆汁酸与甘氨酸或牛磺酸的偶联物。胆汁盐由四种不同的胆汁酸组成：胆酸、脱氧胆酸、鹅去氧胆酸和石胆酸。
胆汁盐是在受控条件下由纯化的新鲜胆汁提取出来，可用于细菌培养基，在细胞培养基中它作为一种选择性抑制剂，可以分离和鉴定病原体。例如，麦康凯琼脂/肉汤
應用
在进行的实验中，胆汁盐可以用作选择性试剂之一，以防止受损的大肠杆菌细胞的生长，以鉴定选择性培养基中的特异性试剂，其将抑制受损的大肠杆菌 ML30 细胞的生长。它也可以用于创伤弧菌（贝内克氏菌属）的分离鉴定，它是一种嗜盐菌，可导致几种人类传染病。
生化／生理作用
胆汁盐是表面活性的类固醇化合物，它们的主要生理功能是帮助消化脊椎动物肠道中的亲脂性营养素。
