Application

1,3-Dioleoyl-2-palmitoylglycerol (OPO) has been used:
  • as a synthetic triacylglycerol (TAG) standard to investigate the fragmentation patterns of TAGs in milk fat by the multi-dimension mass spectrometry (MDMS) method
  • as a lipid standard to analyze OPO content/TAG compositions in the acidolysis products by high-performance liquid chromatography-evaporative light scattering detector (HPLC-ELSD)
  • as a standard in silver-ion HPLC separation of OPO-rich human milk fat substitute (HMFS)

Biochem/physiol Actions

1,3-Dioleoyl-2-palmitoylglycerol (OPO) exerts several beneficial effects on infants, including remitting constipation, improved calcium and fatty acid absorption, and improved bone development.

General description

1,3-Dioleoyl-2-palmitoylglycerol (OPO) is a structured triglyceride in infant formula. Its structure is like human milk fat (HMF).

1,3-Dioleoyl-2-palmitoylglycerol (OPO)-rich human milk fat substitute (HMFS) was synthesized from tripalmitin-rich fraction and ethyl oleate by a lipase-catalyzed interesterification. Response surface methodology was employed to optimize its OPO content and acyl migration with reaction factors - substrate mole ratio of

Milk fat is arguably one of the most complex fats found in nature and varies widely between animal species. Analysis of its digestion products is tremendously challenging, due to the complexity, diversity, and large range of concentrations of triacylglycerols (TAGs)
