The metabolic distinctiveness of emulsified lipid particles in the bloodstream and its clinical implications

  • Keiji Iriyama
Review Article


The advantages of administering intravenous fat emulsions are well known. Primarily, they are important sources of essential fatty acids; they allow the administration of many calories within a small volume; and they are isotonic compared to body fluid. In this review, the metabolic distinctiveness of parenterally infused fat particles in the bloodstream is evaluated under four main headings: (1) the structure and metabolism of fat emulsion particles; (2) the metabolism of phospholipid-rich fat emulsion; (3) the interactions between fat emulsion particles and plasma lipoproteins; and (4) the acquisition of protein moieties (apolipoproteins) by fat emulsion particles and its clinical implications.
