the highest proportions of leucine-enkephalin were found in the cerebral cortex and hippocampus.6 formaldehyde perfusion and fixation of the brain in vivo had no significant effect on the brain content of enkephalin , indicating that proteolytic breakdown is not a major problem in the extraction of these peptides.7 it is suggested that the enkephalins may have a neurotransmitter role in both brain and peripheral tissues and that methionine- and leucine-enkephalin may subserve separate neuronal functions .
