title: In-situ observation of tryptophan in larval cocoon silk of the hornet Vespa simillima xanthoptera cameron by ultraviolet resonance raman spectroscopy.
abstract: We performed in-situ ultraviolet resonance Raman (UVRR) spectroscopy of the larval cocoon silk of the hornet, Vespa simillima xanthoptera Cameron, and compared the result with that of the silkworm, Bombix mori. The UVRR spectrum of the hornet cocoon differed markedly from that of the B. mori cocoon: peaks attributable to tyrosine (Tyr) were observed strongly, and tryptophan (Trp) peaks weakly, in the spectrum of the B. mori cocoon, whereas peaks attributable to Trp exclusively appeared in the spectrum of the hornet cocoon.
