Bile salts of frogs: a new higher bile acid, 3 alpha, 7 alpha, 12 alpha, 26-tetrahydroxy-5 beta-cholestanoic acid from the bile Rana plancyi.

Journal of Lipid Research, 1980
Bile salts of ten species of frogs of the family Ranidae were examined by means of thin-layer chromatography, gas-liquid chromatography, and gas-liquid chromatography-mass spectrometry. Their major bile alcohols were ranol, cyprinol, or bufol.

C26-Analogs of naturally occurring C27 bile alcohols

Journal of Lipid Research, 1976
C26 Bile of the 24-nor-5β-cholestane series were prepared starting from methyl cholate. A Grignard reaction of methyl magnesium iodide with methyl cholate yielded 24-nor-5β-cholestane-3α,7α,12α,25-tetrol which was dehydrated to form a mixture of 24-nor ...

Pathophysiology and Treatment of Lipid Abnormalities in Cerebrotendinous Xanthomatosis: An Integrative Review

Brain Sciences, 2023
Cerebrotendinous xanthomatosis (CTX) is an autosomal recessive disorder caused by pathogenic variants in CYP27A1, leading to a deficiency in sterol 27-hydroxylase.

Absolute configuration of pentahydroxy bile alcohols excreted by patients with cerebrotendinous xanthomatosis: a circular dichroism study

Journal of Lipid Research, 1978
The absolute configurations of the C27 pentahydroxy bile alcohols present in bile and feces of two patients with cerebrotendinous xanthomatosis (CTX) were determined by circular dichroism (CD) spectroscopy.
