Reinvestigation of surfactin, a previously studied peptidolipid surfactant from Bacillus subtilis, by fast-atom-bombardment mass spectrometry and 1H-NMR spectroscopy, as well as by chemical methods, revealed the presence of a closely related second constituent. This new compound, [Val7]surfactin, differs from the known surfactin by the C-terminal amino acid residue which is valine instead of leucine.
通过快原子轰击质谱法、¹H-核磁共振光谱法以及化学方法，对一种之前已研究过的来自枯草芽孢杆菌的脂肽表面活性剂表面活性素进行重新研究，结果显示存在一种与之密切相关的第二种成分。这种新化合物[Val⁷]表面活性素与已知的表面活性素的不同之处在于其C端氨基酸残基，已知表面活性素的C端氨基酸残基是亮氨酸，而[Val⁷]表面活性素的是缬氨酸。
