1,3-二油酸-2-棕榈酸甘油三酯（OPO）是婴儿配方奶粉中的结构化甘油三酸酯。它的结构类似人类乳脂（HMF）。 应用 1,3-二油酸-2-棕榈酸甘油三酯（OPO）已用于： 作为合成三酰甘油（TAG）标准品，通过多维质谱（MDMS）法研究乳脂中TAG的裂解规律； 作为脂质标准品，通过高效液相色谱-蒸发光散射检测器（HPLC-ELSD）分析酸解产物中的OPO含量/TAG组成； 作为标准品，用于富OPO人乳脂替代品（HMFS）的银离子HPLC分离。 1,3-Dioleoyl-2-palmitoylglycerol (OPO) is a structured triglyceride in infant formula. Its structure is like human milk fat (HMF). 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).
