A new sensitive and specific method for the evaluation of 3 beta-hydroxysteroid delta 7-reductase activity, the defective enzyme in the Smith-Lemli-Opitz (SLO) syndrome, is described. The assay is based on the use of gas chromatography-mass spectrome

The Smith-Lemli-Opitz syndrome is caused by an inherited defect in 7-dehydrocholesterol-delta7-reductase, the enzyme that catalyzes the last reaction in cholesterol biosynthesis, the conversion of 7-dehydrocholesterol to cholesterol. As a result, def

We have identified the third unknown sterol in the plasma and tissues of Smith-Lemli-Opitz homozygotes as 19-nor-5,7,9(10)-cholestatrien-3 beta-ol. The structure was established from capillary gas-liquid chromatography retention index and characteris

The Smith-Lemli-Opitz syndrome is a common birth defect syndrome characterized biochemically by low plasma cholesterol levels and high concentrations of the cholesterol precursor 7-dehydrocholesterol. The present study was undertaken to prove that th

Cholesta-5,8-dien-3 beta-ol (8-dehydrocholesterol) and cholesta-5,7-dien-3 beta-ol (7-dehydrocholesterol) were isolated from the fecal neutral sterol fraction from homozygotes with Smith-Lemli-Opitz syndrome. The structures of the sterols were conclu

The Smith-Lemli-Opitz syndrome is an autosomal recessive birth defect (frequency 1:20,000-1:40,000) that results in profound mental retardation, physical deformities, and failure to thrive. It is characterized biochemically by low plasma cholesterol

We investigated the relationship between plasma cholestanol (5 alpha-dihydrocholesterol) concentrations and the activity and mRNA levels of cholesterol 7 alpha-hydroxylase, the rate-controlling enzyme for bile acid synthesis, in three female sitoster

We investigated the effects of cholesterol, cholestyramine, and taurocholate feeding on steady state specific activities and mRNA levels of hepatic 3-hydroxy-3-methylglutaryl (HMG)-CoA reductase and cholesterol 7 alpha-hydroxylase in the rat. Interru

The configuration at C-25 in 5 beta-cholestane-3 alpha, 7 alpha, 12 alpha,25,26-pentol isolated from the bile and feces of patients with cerebrotendinous xanthomtosis (CTX) was determined from the lanthanide-induced circular dichroism (CD) Cotton eff

This paper describes syntheses of 5β-cholestane-3α, 7α, 12α, 25-tetrol and 5β-cholestane-3α, 7α, 12α, 24ξ, 25-pentol which give higher yields than previously published methods. In addition, 5β-cholestane-3α, 7α, 12α, 24ξ, 25-pentol was
