In vivo incorporation of exogenous stearic acid in synaptosomes: high occurrence of non-esterified fatty acids.
Subcutaneously injected stearic acid is taken up by the brain through the 'blood-brain barrier' and is incorporated into synaptosomal lipids (as well as into other brain compartments). Phospholipids are potent acceptors (choline phosphatides, ethanolamine phosphatides, serine phosphatides). Moreover a high level of radioactivity was found in non-esterified fatty acids.
