Editing Lecithin (section)

===Hydrolysed lecithin===
To modify the performance of lecithin to make it suitable for the product to which it is added, it may be hydrolysed enzymatically. In hydrolysed lecithins, a portion of the phospholipids have one fatty acid removed by [[phospholipase]]. Such phospholipids are called lysophospholipids. The most commonly used phospholipase is phospholipase A2, which removes the [[fatty acid]] at the C2 position of glycerol. Lecithins may also be modified by a process called [[fractionation]]. During this process, lecithin is mixed with an alcohol, usually [[ethanol]]. Some phospholipids, such as phosphatidylcholine, have good solubility in ethanol, whereas most other phospholipids do not dissolve well in ethanol. The ethanol is separated from the lecithin sludge, after which the ethanol is removed by evaporation to obtain a phosphatidylcholine-enriched lecithin fraction.{{citation needed|date=January 2025}}
