Mass spectrometric identification of C20 fatty acids bovine lens using the pyrrolidide derivative
Autor: Anthony J. Valicenti, Ralph T. Holman, J. R. Chipault, Clifford J. Chapman
Publikováno v: Lipids. 13:190-194
Unsaturated C20 fatty acids from bovine lens have been examined via gas chromatography-mass spectrometry of their pyrrolidide derivatives. The presence of arachidonic acid and 5,8,11-20:3 in bovine lens has been confirmed by this study. In addition,

Lipids of the moss,Ceratodon purpureus, yield up to 25% of an acetylenic acid which was identified as allcis-9,12,15-octadecatrien-6-ynoic acid. The methyl ester of this acid was isolated in 95% purity by gas liquid chromatography. Mass spectroscopy

Lipid composition and ( activity in rat lens during triparanol-induced cataract formation
Autor: Douglas R. Pfeiffer, J. R. Chipault, George R. Mizuno, Clifford J. Chapman
Publikováno v: Biochimica et Biophysica Acta (BBA) - Biomembranes. 644:1-12
The development of triparanol cataracts in rats is accompanied by the loss of lens ( Na + + K + )- ATPase activity and by the alterations in the lens content and composition of phospholipids, sterols and phospholipid acyl groups. The lipid changes oc

The determination of conjugatedcis-trans andtrans-trans methyl octadecadienoates by infrared spectrometry
Autor: J. M. Hawkins, J. R. Chipault
Publikováno v: Journal of the American Oil Chemists Society. 36:535-539
Pure conjugated methylcis-trans andtrans-trans octadecadienoates have been prepared and used to develop a method for the determination of these compounds by infrared spectrometry.Cis-trans compounds alone or in the presence oftrans-trans conjugation

Rapid micromethod for locating the oxirane group in 1,2-epoxides
Autor: G. R. Mizuno, J. R. Chipault, E. C. Ellison
Publikováno v: Microchemical Journal. 14:227-234
A procedure for the analysis of micro amounts of epoxides is described. The method is based on the splitting of epoxides by periodic acid in a nonaqueous medium, followed by direct analysis of the reaction mixture by gas chromatography. The procedure
