Hoyo Pérez, Javier; Guaus Guerrero, Ester; Torrent Burgués, Juan; Sanz Carrasco, Fausto (2015-05-01)
Article
Restricted access - publisher's policyPhotosynthetic organisms use light to convert the inorganic matter in organic one. Photosynthetic process consists on several steps, and one of them involves plastoquinone (PQ) that acts as electron and proton shuttle ... -
Biomimetic monolayer films of monogalactosyldiacylglycerol incorporating ubiquinone
Hoyo Pérez, Javier; Torrent Burgués, Juan; Guaus Guerrero, Ester (2012-09-01)
Article
Open AccessUbiquinone and plastoquinone are two of the main electron and proton shuttle molecules in biological systems, and monogalactosyldiacylglycerol (MGDG) is the most abundant lipid in the thylakoid membrane of chloroplasts. ... -
