Collisional Spectroscopy in Structural Characterization of Melanins: I. A First Study on |C8H7ON|+· Ions Originating From Pyrolysis of Biosynthetic and Synthetic Tryptophan Melanins
The structural investigation of four bio- and synthetic melanins, obtained by the action of polyphenol oxidase from potatoes and Psalliota campestris mushrooms and of tyrosinase from Sepia officinalis on tryptophan, or by means of performic oxidation, has been carried out by thermal decomposition pe...

Collisional Spectroscopy in Structural Characterization of Melanins: I. A First Study on |C8H7ON|+· Ions Originating From Pyrolysis of Biosynthetic and Synthetic Tryptophan Melanins |
| abstract |
The structural investigation of four bio- and synthetic melanins, obtained by the action of polyphenol oxidase from potatoes and Psalliota campestris mushrooms and of tyrosinase from Sepia officinalis on tryptophan, or by means of performic oxidation, has been carried out by thermal decomposition performed in the ion source of a mass spectrometer. The structural characterization of the ionic species |C8H7ON|+· common and abundant for all the examined compounds, has been obtained by accurate mass measurements and collisional spectroscopy. These mass spectrometric techniques have shown unequivocally for ionic species | C8H7ON| +· the structure of 2-indolinone. |

The structural characterization of the ionic species |C8H7ON|+· common and abundant for all the examined compounds, has been obtained by accurate mass measurements and collisional spectroscopy. These mass spectrometric techniques have shown unequivocally for ionic species | C8H7ON| +· the structure of 2-indolinone.</subfield></datafield><datafield tag="533" ind1=" " ind2=" "><subfield code="d">2006</subfield><subfield code="f">Blackwell Publishing Journal Backfiles 1879-2005</subfield><subfield code="7">|2006||||||||||</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Thermal decomposition</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">BIASIOLO, MONICA</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">PRISON, GIAMPIETRO</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">PELLI, BEATRICE</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">TRALDI, PIETRO</subfield><subfield code="4">oth</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">In</subfield><subfield code="t">Periodontology 2000</subfield><subfield code="d">Oxford [u.a.] : Wiley-Blackwell, 1993</subfield><subfield code="g">1(1987), 2, Seite 0</subfield><subfield code="h">Online-Ressource</subfield><subfield code="w">(DE-627)NLEJ243925956</subfield><subfield code="w">(DE-600)2027098-7</subfield><subfield code="x">1600-0757</subfield><subfield code="7">nnns</subfield></datafield><datafield tag="773" ind1="1" ind2="8"><subfield code="g">volume:1</subfield><subfield code="g">year:1987</subfield><subfield code="g">number:2</subfield><subfield code="g">pages:0</subfield></datafield><datafield tag="856" ind1="4" ind2="0"><subfield code="u">http://dx.doi.org/10.1111/j.1600-0749.1987.tb00395.x</subfield><subfield code="q">text/html</subfield><subfield code="x">Verlag</subfield><subfield code="z">Deutschlandweit zugänglich</subfield><subfield code="3">Volltext</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_USEFLAG_U</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">ZDB-1-DJB</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_NL_ARTICLE</subfield></datafield><datafield tag="951" ind1=" " ind2=" "><subfield code="a">AR</subfield></datafield><datafield tag="952" ind1=" " ind2=" "><subfield code="d">1</subfield><subfield code="j">1987</subfield><subfield code="e">2</subfield><subfield code="h">0</subfield></datafield></record></collection>
