The nature of the processes at the origin of life that selected specific classes of molecules for broad incorporation into cells is controversial. Among those classes selected were polyisoprenoids and their derivatives. This paper tests the hypothesis that polyisoprenoids were early contributors to membranes in part because they (or their derivatives) could facilitate charge transport by quantum tunneling...
Unempfindlich: Eine Serie von Molekülen mit gleicher Kopfgruppe und Kohlenstoffkette, aber unterschiedlichen Endgruppen R wurde in Kontakten vom Typ Ag/S(CH2)4CONH(CH2)2R//Ga2O3/EGaIn eingesetzt (siehe Bild), um die Geschwindigkeit des Ladungstransports durch Tunneln zu studieren. Ein Variieren zwischen aliphatischen, aromatischen und heteroaromatischen R hatte keinen signifikanten Einfluss auf die...
