Improved quantitation of plasma lipids by direct gas-liquid chromatography

open access: yesJournal of Lipid Research, 1969
A preliminary digestion of total plasma lipid extracts with phospholipase C, which converts the lysolecithins, lecithins, and sphingomyelins into monoglycerides, diglycerides, and ceramides, respectively, has been shown to facilitate subsequent ...

EFFECT OF SEASONAL VARIATIONS ON LIPID COMPONENTS IN THREE NILE FISH SPECIES [PDF]

open access: yesAssiut Veterinary Medical Journal, 1987
A comparative detailed study was carried out on three Nile fish species, namely: Tilapia nilotica, Clarias lazera and Synodon tis schall. Lipid components were determined by thin layer chromatography (TLC) during the fishing season 1984/1985.

A comparison of procedures to determine free fatty acids in rat heart

open access: yesJournal of Lipid Research, 1978
The level of free fatty acids in intact tissues has been found to be low but is known to rise in proportion to the extent of autolysis. Therefore, the high levels of free fatty acid reported in the cardiac lipids of rats fed rapeseed oil were ...
