| Research Abstract |
Since the first fatty acid amino acid conjugate (FAC) was isolated from regurgitant of Spodoptera exigua larvae, their role as elicitors of induced responses in plants has been well documented. However, studies of the biosyntheses as well as the physiological role of FACs in the insect have been minimal. By utilizing ^<14>C-labeled glutamine, glutamic acid and linolenic acid in feeding studies of S.litura larvae, combined with tissue analyses, we found that FACs play an active role in nitrogen assimilation in Lepidoptera larva and that glutamine containing FACs in the gut lumen may function as a form of storage of glutamine.
