Solvent Fractionation - American Oil Chemists' Society
By adding solvent one needs to think of percentage crystals (or solid) in the total liquid of solvent and remaining liquid oil. For example, crystallising 60% of the oil with 5 volumes of solvent to 1 of oil will actually only be 10% for this solvent fractionation and therefore still a liquid slurry.
This site is for students, technologists, scientists, and laypersons to learn more about lipid chemistry and technology. The website is owned and managed by AOCS, but the scientific content is under the direction of the editorial team.

Comparative evaluation of solvent extraction methods
Journal of the American Oil Chemists' Society. Volume 60, Issue 4. Article. Comparative evaluation of solvent extraction methods for the determination of neutral and polar lipids in beef. M. R. Sahasrabudhe. Food Research Institute, Agriculture Canada, K1A 0C6 Ottawa, Ontario, Canada.
Background One of the most basic needs of mankind is an abundant and reliable food supply. In the modern world, one major source of protein and vegetable oil is from oilseeds, particularly the soybean – an abundant resource which is largely processed using solvent extraction, an efficient and reliable means to separate the high-protein meal solids from the high-energy edible oil.
Solvent extraction of lipid components from egg yolk
The effects of solvent systems on extraction of lipid components from commercially spray‐dried egg yolks were investigated. Hexane, hexane:isopropanol (2:1), and chloroform:methanol (2:1) were studied, and the effects of temperature of extraction and ratio of solvent to egg were examined in a 3×2×2 factorial design.
The science of lipidomics has been defined as "the full characterization of lipid molecular species and of their biological roles with respect to expression of proteins involved in lipid metabolism and function, including gene regulation".

Phospholipid
Phospholipid synthesis. Phospholipid synthesis occurs in the cytosolic side of ER membrane that is studded with proteins that act in synthesis (GPAT and LPAAT acyl transferases, phosphatase and choline phosphotransferase) and allocation (flippase and floppase). Eventually a vesicle will bud off from the ER containing phospholipids destined for the cytoplasmic cellular membrane on its exterior
