The identity of the moiety (other than glycerol) esterified to the phosphoric group determines the specific phosphoHpid compound. The three most common phosphoHpids in commercial oils are phosphatidylcholine or lecithin [8002-45-5] (3a), phosphatidylethanolamine or cephalin [4537-76-2] (3b), and phosphatidjlinositol [28154-49-7] (3c). These materials are important constituents of plant and animal membranes. The phosphoHpid content of oils varies widely. Laurie oils, such as coconut and palm kernel, contain a few hundredths of a percent. Most oils contain 0.1 to 0.5%. Com and cottonseed oils contain almost 1% whereas soybean oil can vary from 1 to 3% phosphoHpid. Some phosphoHpids, such as dipaLmitoylphosphatidylcholine (R = R = palmitic R" = choline), form bilayer stmetures known as vesicles or Hposomes. The bdayer stmeture can microencapsulate solutes and transport them through systems where they would normally be degraded. This property allows their use in dmg deHvery systems (qv) (8). 

Place 1 g of potassium hydrogen sulfate, KHS04, in each of seven clean and dry test tubes. Label them. Add a few grains of your pure preparations, lecithin and cholesterol, to two of the test tubes. Add a drop, about 0.1 g, from each, glycerol, com oil, butter, and egg yolk to the other four test tubes. To the seventh test tube add a few crystals of sucrose. 

The stracture of the multilayered emulsions may be preserved during spraydrying, enabling the delivery of emulsions with multilayered interfaces in a powder format. Spray-dried tuna oil powders made from emulsions containing oil droplets with lecithin-chitosan membranes, with added com symp showed good oil retention and water dispersibility (Klinkesom et al. 2006). 

Vitamins B, (pantothenic acid), Bg (pyridoxine). By (biotin), Bg (inositol), B,o (para-aminobenzoic acid), Bn (choline), lecithin, and Bi5 (pangamic acid) are Usted here for sake of completeness but not shown in the table.The reader is referred to http //www.acu-ceU.com for examples. 

Sunflower lecithin is not produced in considerable amounts worldwide. This is mainly because of the low lecithin content of crude sunflower oil as compared with 2.9% for soybean, 1.9% for canola, 2.4% for cottonseed, and 2.0-2.7% for com oil (normalized at 70% of insolubles in acetone). Lecithin removal from sunflower oil may be justified in strong sunflower producer countries. It may be used as a food additive in view of its high phosphatidylcholine and essential fatty acid content. Upon refining and fractioning stages, the quality of sunflower lecithin may be improved for the manufacture of food products and cosmetics. 

Both the glycolipids and the phospholipids of corn have lower percentages of linolenic acid (18 3) and are more saturated than those in the soybean. In general, cmde corn and soybean lecithins are equal in linoleic acid (18 2) content, but lino-leic acid in corn varies from 42% to 70% depending on the variety of corn. Phytic acid, 88% of which is in the com germ, is extracted as part of the lecithin fraction (32, 37). Elimination of phytic acid in com is desirable because it binds zinc, magnesium, and calcium.

The major lecithin sold domestically in commercial quantities is extracted from soybeans. Com and sunflower seed lecithins are available in limited amounts. Canola is being reviewed as a lecithin source in countries that do not grow significant quantities of soybeans. Lecithins may be added to feeds in cmde or refined forms, remain as residuals in solvent- or mechanical-extracted oilseed meals, be returned to oilseed meals as extracted gums or soapstocks at combined solvent extraction-oil refinery operations, or simply be native to an oilseed fed whole.
