Identification of mono- and dihydroxy bile acids in human feces by gas-liquid chromatography and mass spectrometry

open access: yesJournal of Lipid Research, 1966
The mono- and disubstituted cholanoic acids present in human feces have been investigated. Extracts of feces were fractionated on silicic acid column and individual bile acids were isolated by preparative thin-layer chromatography. The isolated compounds

Brain lipids: I. Quantification and fatty acid composition of cerebroside sulfate in human cerebral gray and white matter

open access: yesJournal of Lipid Research, 1964
Cerebroside sulfate was isolated by column chromatography from infant whole brains and adult human cerebral grey and white matter. Fatty acid analyses, performed by gas-liquid chromatography (GLC), of normal and α-hydroxy fatty acids obtained after ...

Fatty Acyl Esters of Hydroxy Fatty Acid (FAHFA) Lipid Families

open access: yesMetabolites, 2020
Fatty Acyl esters of Hydroxy Fatty Acids (FAHFA) encompass three different lipid families which have incorrectly been classified as wax esters. These families include (i) Branched-chain FAHFAs, involved in the regulation of glucose metabolism and ...

Fatty acids of human brain cerebrosides*

open access: yesJournal of Lipid Research, 1961
Four regions of two human brains were analyzed for the individual cerebroside acids: cerebral cortex white and gray matter, cerebellum (mainly gray matter), and corpus callosum.

Studies of brain myelin in the “quaking mouse”

open access: yesJournal of Lipid Research, 1971
Myelin was isolated from the brains of “quaking” and littermate control animals and its composition was determined. The brains of quaking animals contained approximately one-fourth as much myelin as the control animals.

Distribution of molecular species of sphingomyelins in different parts of bovine digestive tract

open access: yesJournal of Lipid Research, 1975
Sphingomyelins were isolated from mucosal layers of bovine rennet stomach, duodenum, jejunoileum, and colon ascendens. The ceramides obtained after phospholipase degradation were characterized by thin-layer chromatography, mass spectrometry, and gas ...

Artifacts produced by acidic hydrolysis of lipids containing 3-hydroxyalkanoic acids

open access: yesJournal of Lipid Research, 1974
After acidic hydrolysis of lipid A preparations from pseudomonads, products containing both hydroxy and nonhydroxy fatty acids were obtained. The major products were alkanoate esters of the hydroxy acids.

Fatty acid metabolism in Serratia marcescens: IV. The effect of temperature on fatty acid composition

open access: yesJournal of Lipid Research, 1963
An analysis of the fatty acids of Serratia marcescens grown at different temperatures shows that three medium-chain hydroxy acids, present in cells grown at 30°, are greatly decreased in quantity when the cells are grown at 37°.
