Application

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.

Actions biochimiques/physiologiques

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.

Notes préparatoires

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

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);

We performed differential scanning calorimetry (DSC) and Fourier transform infrared (FTIR) spectroscopic measurements to study the effects of lathosterol (Lath) on the thermotropic phase behavior and organization of dipalmitoylphosphatidylcholine (DPPC) bilayer membranes and compared our results with those previously reported

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

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
