Structure of HACC was characterized by infrared spectrum and C13 NMR ￡-and it is proved that substitution reaction mainly occurs on the-N element.

While these findings were not surprising, the high levels of C13 in the L.emarginatus ant species, certainly was, given that they live close to humans.

这样的结果并不那么两人吃惊，L.emarginatus蚂蚁体内含C13也多，因为它们生活的最靠近人类。
