The ability of the dietary lipids to modulate this function is described. It was demonstrated that the ionic apical permeability of the enterocytes are related to their membrane lipid composition. The importance of the essential fatty acids is emphasized. The time course changes of the apical permeability are of value in improving sea water adaptation, similar conclusions are reported for Nacl supplementation. PY 1983 PD DEC CT Actes de colloques.
