Effects on light-emission were similar to those on O2 uptake. The chemiluminescence of the present system was sensitive to cyanide and to the radical trap 2,5-di-t-butylquinol, indicating a catlytic activity of cytochrome c and the presence of free-radical species respectively. Lipid-vesicle enhanced chemiluminescence showed different kinetic behaviours, apparently depending on unsaturation: three phases are described for soya-bean phosphatidylcholine, whereas only one phase was present in mixtures containing dipalmitoyl and dioleoyl phospholipids. Chemiluminescence of lipid vesicles supplemented with cytochrome c and hydroperoxide showed similar kinetic patterns with H2O2 and primary (ethyl) and tertiary (t-butyl and cumene) hydroperoxides. Participation of singlet molecular oxygen, mainly on the phase III of chemiluminescence, is suggested by the increase of light-emission by 1,4-diazabicyclo[2.2.2]-octane as well as by data from spectral analysis.<\/jats:p>","DOI":"10.1042\/bj1880577","type":"journal-article","created":{"date-parts":[[2015,8,10]],"date-time":"2015-08-10T20:22:37Z","timestamp":1439238157000},"page":"577-583","update-policy":"https:\/\/doi.org\/10.1042\/crossmark_policy","source":"Crossref","is-referenced-by-count":34,"title":["Chemiluminescence of lipid vesicles supplemented with cytochrome <i>c<\/i> and hydroperoxide"],"prefix":"10.1042","volume":"188","author":[{"given":"E","family":"Cadenas","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"A","family":"Boveris","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"B","family":"Chance","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"288","container-title":["Biochemical Journal"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/portlandpress.com\/biochemj\/article-pdf\/188\/3\/577\/619361\/bj1880577.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"syndication"},{"URL":"https:\/\/portlandpress.com\/biochemj\/article-pdf\/188\/3\/577\/619361\/bj1880577.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2021,11,26]],"date-time":"2021-11-26T18:03:36Z","timestamp":1637949816000},"score":1,"resource":{"primary":{"URL":"https:\/\/portlandpress.com\/biochemj\/article\/188\/3\/577\/12133\/Chemiluminescence-of-lipid-vesicles-supplemented"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1980,6,15]]},"references-count":0,"journal-issue":{"issue":"3","published-print":{"date-parts":[[1980,6,15]]}},"URL":"https:\/\/doi.org\/10.1042\/bj1880577","relation":{},"ISSN":["0264-6021"],"issn-type":[{"value":"0264-6021","type":"print"}],"subject":[],"published":{"date-parts":[[1980,6,15]]}}}
