Abstract:Pure cerebrosides, sphingomyelines, lecithines and neutral fats were isolated from brains of young rats 6 and 72 hours after intracerebral injection of 14C acetate. We detected the composition of their fatty acids and determined the specific activities. The highest value was always found in palmitic acid which obviously is the precursor for the formation of the other fatty acids. The applied activity incorporated in the fatty acids of lecithines and neutral fats was much higher than the amount concerning cereb… Show more
“…Die spezifischen Hirnlipide, deren Fettsauren, wie wir mit radioaktivem Acetat zeigten [3], einen viel langsameren Turnover aufweisen als diejenigen der Lecithine, sind in jungen Gehirnen also in viel geringerer Konzentration als bei Erwachsenen vorhanden.…”

Five brains of 6 weeks old children have been examined by previously published methods. Pure lipids from different brain regions have been separated into various fractions.
