Aplicación

5α-Cholest-7-en-3β-ol was used as a substrate in enzymatic assay for plasma cholesterol. It was used to supplement diet of Daphnia galeata to study the effect on life-history traits.

Acciones bioquímicas o fisiológicas

5α-Cholest-7-en-3β-ol (Lathosterol) is an intermediate in cholesterol biosynthesis pathway. Lathosterol in serum is carried on lipoproteins and is indicative of the rate of cholesterol synthesis. It acts as a marker of synthesis of cholesterol and is not affected by dietary consumption of cholesterol.

Nota de preparación

5α-Cholest-7-en-3β-ol yields clear, colorless solution in chloroform at 10 mg/ml.

The metabolism of Delta(7)-cholestenol, cholesterol, and cholestanol was examined in a patient with cerebrotendinous xanthomatosis after intravenous pulse-labeling with a mixture of dl-[2-(14)C]mevalonate and stereospecific 3S,4S,3R,4R-[4-(3)H]mevalonate. Silver nitrate and reversed-phase thin-layer chromatography were used to purify the sterols isolated from

Host-plant specialization plays a key role in insect evolution, but little is known about its molecular basis. A new paper shows that a cactus-feeding fly became restricted to its host by changes in an enzyme that converts dietary sterols into

Deuterium-labeled 5alpha-cholest-7-en-3beta-ol (1) bearing one or two deuteriums at the C-5alpha and (or) C-6alpha positions was synthesized in high isotopic and chiral purity. These compounds were used as substrates with the microsomal wild-type Zea mays and recombinant Arabidopsis thaliana Delta(7)-sterol-C5(6)-desaturases

We measured serum lathosterol levels and whole body cholesterol synthesis by sterol balance in 12 human subjects on a metabolic ward in four randomly allocated, 6-7 week periods: 1) lovastatin (40 mg b.i.d.) + low cholesterol diet (mean 246 mg/day);

From the butanol fraction of the starfish Asterina pectinifera Müler et Troschel (Asteriidae), we have isolated a new component, 5alpha-cholest-7-en-3beta-ol. Its antigenotoxic and antimutagenic activities were examined by the SOS chromotest with Escherichia coli PQ37 and by Ames test with
