Plant Phosphatides. II of In addition, the acid was identified by conversion into elaidic acid melting at ”C. The problem of the character of the glycerophosphoric acid2 of plant lecithin . the properties of the phosphatides when titrated in non-aqueous media. An electrometric titration system in which a solvent mixture which dis- solves a large number of lipides is employed has been developed. The dipalmitoyl-L-c+glycerophosphoric acid. acid substituents can occur theoretically in any of six stereoisomeric forms, i.e. four a and two {3 forms. Recent investigations (8, 24, 25) seen~ to indi­ cate that the glycerophosphoric acid moiety of natural phosphatides . Moreover, glycerophosphorylcholine obtained by enzymatic hydrolysis of pancreatic phosphatides possesses structure a'4": the dipalmitophosphatidylcholine extracted from beef brain is identicalln with the synthetic a isomeru; finally, the acetalphosphatide crystallised from brain gives rise to the a-glycerophosphoric acid.

The object of the present work has been to study those soybean phosphatides which cannot be extracted by means of nonpolar solvents but only be means of mixtures of nonpolar and polar solvents, for instance hexane and ethanol.

Using the recent method of Karrer, it has been shown that the β form of glycerophosphoric acid exceeds the a form in the phosphatides of human brain, adult, newborn and fetal, as in other phosphatides. 2 ingtotheschemeofRosenheim-*-lipoidsare dividedinto- (1)Cholesteringroup,freefromnitrogenandphosphorous (2)Cerebrogalactosides.
