Phosphatidyl serine
Phosphatidyl serine, also known as diacylglyceryl phosphate serine, phosphatidyl serine phosphatidylserine, complex neric acid, is a widely existed phospholipid, phosphatidyl serine is white waxy solid or light yellow loose powder, insoluble in methanol, ethanol, anhydrous acetone, soluble in ether, petroleum ether, chloroform, emulsified in water, the molecular formula is C42H82NO10P. The relative molecular mass is 792, the melting point is 135℃, the boiling point is 165℃, and the flash point is 335℃.
When exposed to air, phosphatidyl serine is easily oxidized, and its color gradually darkens, from white to yellow to black. Generally, phosphatidyl serine is almost not affected by the saturated state of phosphatidyl serine and alcohol can form a cross-chain gel.
If phosphatidyl serine is dissolved in water, except for a very small part of the phosphatidyl serine will form a true solution, most of the other insoluble lipids form small groups.
