Human urinary sulfatides in patients with sulfatidosis (metachromatic leukodystrophy)

open access: yesJournal of Lipid Research, 1971
The excretion of sulfatides in human urine was studied. 24-hr urine collections were filtered. Urinary glycolipids were extracted from the filter paper and fractionated on diethylaminoethyl cellulose and silicic acid columns, and by thin-layer ...

Isolation and characterization of glucosylsphingosine from Gaucher's spleen

open access: yesJournal of Lipid Research, 1974
Glucosylsphingosine has been isolated for the first time as a natural constituent from Gaucher's spleen. On thinlayer chromatography, it migrates with authentic glucosylsphingosine, yielding a positive color reaction with ninhydrin for the amino group ...

Branched-chain and odd-numbered fatty acids and aldehydes in the nervous system of a patient with deranged vitamin B12 metabolism

open access: yesJournal of Lipid Research, 1973
A mixture of isomers of methylhexadecanoic acid was isolated from glycerolipids of brain, spinal cord, and sciatic nerve of a patient who died from methylmalonic aciduria, a disease in which vitamin B12 is not converted to deoxyadenosyl B12.

Quantitative analysis of brain galactosylceramides by high performance liquid chromatography of their perbenzoyl derivatives

open access: yesJournal of Lipid Research, 1976
A high performance liquid chromatographic (HPLC) method for analysis of galactosylceramides as their benzoyl derivatives has been devised. Samples containing 10-150 nmoles of monohexosylceramides are benzoylated by heating for 60 min at 60 ° C in 0.5 ml ...

2,3-erythro-Dihydroxyhexacosanoic acid and homologs: isolation from yeast cerebrin phosphate and determination of their structures

open access: yesJournal of Lipid Research, 1973
Homologs of methyl esters of very polar fatty acids were obtained by methanolysis of cerebrin phosphate isolated from baker's yeast. The major ester component was isolated by preparative gas–liquid chromatography and was found to be 2,3 ...

Preparation and analysis of benzoylated cerebrosides

open access: yesJournal of Lipid Research, 1973
The benzoylation of cerebrosides with benzoyl chloride and with benzoic anhydride is described, and the derivatives that contained hydroxy and nonhydroxy fatty acids were isolated by high pressure liquid chromatography (HPLC).
