L-α-Phosphatidylcholine (C09-0936-483)

Product description：L434221 is a crude extract of soybean phospholipids. Typical lots of purified soybean phosphatidylcholine have fatty acid contents of approximately C16:0 (palmitic), C18:0 (stearic), C18:1(oleic), C18:2 (linoleic), and 18:3 (linolenic) with other fatty acids being minor contributors. Purified phosphatidylcholine is soluble in chloroform and ethanol. Other major phospholipid components include phosphatidylethanolamine and inositol phosphatides. Other phospholipids and neutral lipids such as triglycerides, tocopherols, and sterols may be present. Carbohydrates may also be present. A procedure for determination of the amount of oxidation of egg phosphatidylcholine in a liposome preparation by measurement of the oxidation index has been published. The oxidation index is the ratio of the absorbance at 233 nm to the absorbance at 215 nm. The latter wavelength was chosen since there is little contribution of the fatty acid carbonyl to the absorbance at this wavelength, allowing Beer′s Law to be followed. A method of determining choline content has been published.
