| Abstract: |
| Triglycerides (TAG) are the most abundant lipids in breast milk, 1,3-dioleoyl-2-palmitoylglycerol (OPO) and 1-oleoyl-2-palmitoyl-3-linoleoylglycerol (OPL) are the two most abundant TAG in breast milk. Unlike European and American breast milk, which contains more OPO than OPL, Chinese breast milk contains more OPL than OPO, but at present,most infant formula in China is made by adding OPO to simulate breast milk lipids, which is not exactly the same as the TAG composition of Chinese breast milk. To further study the effect of OPL on infant growth and development, the functions of OPL were mainly analyzed from the structure of fatty acid and triglyceride. The contents of OPL in breast milk were compared at home and abroad as well as in many places in China, and the detection methods of OPL isomers were introduced, including silver ion chromatography and liquid chromatography with chiral column combined with atmospheric pressure chemical ionization mass spectrometry for separation and identification. By summarizing the function, content and existing detection techniques of OPL, it aims to provide scientific support for the development of breast milk replacement lipids matching the characteristics of Chinese breast milk. |
