TL;DR: The plasma membrane contained more sterols than other membrane fractions, and the relative proportions of the different sterols were similar in all fractions.
47 citations
TL;DR: In 3- and 14-day-old seedlings and in the leaves of Calendula officinalis the following sterols were identified: cholestanol, campesterol, sitosterol,24-methylcholesta-5,22-dien-3β-ol, 24-methylenecholesterol, stigmasterol and clerosterol.

TL;DR: The presence of 3 plant sterols, β-sitosterol, campesterol, and stigmasterol, has been demonstrated in the serum from 2 patients with β- sitosterolemia and xanthomatosis.

TL;DR: The following sterols were found in the roots, stems, leaves, unripe and ripe fruits of Solanum dulcamara : cholesterol, sitosterol, stigmasterol, campesterol, brassicasterol, isofucosterol and 24-methylenecholesterol.

TL;DR: Human intestinal specificity toward sterols was studied by a balance method in 10 hyperlipoproteinemic patients fed plant sterol mixture with chromium sesquioxide as fecal flow marker, and the recovery of sterols from patients was unrelated to their 5beta-reduction in the intestine.
Abstract: Human intestinal specificity toward sterols was studied by a balance method in 10 hyperlipoproteinemic patients fed plant sterol mixture with chromium sesquioxide as fecal flow marker. The mean fecal recovery of campesterol (C28) was 20 % less than that of β-sitosterol (C29). This difference persisted when corrected for fecal flow (by marker recovery), indicating differences in their intestinal uptake (C28 > C29). The ratio of fecal cholesterol to its 5β-reduction products was lower than that of β-sitosterol in all patients; in vitro, 5β-reduction of both sterols was similar. The recovery of sterols from patients was unrelated to their 5β-reduction in the intestine. In sterol balance studies it is essential to measure cholesterol and plant sterols in the diet and to differentiate cholesterol and its transformation products from plant sterols and their products (Subbiah, 1972).

TL;DR: Flowers and fruits were found to contain a glycoside fraction in which stigmasterol, together with some sitosterol, could be detected.
Abstract: Sterols have been isolated from both adult and juvenile ivy in free and esterified form. Stigmasterol or its C-24 isomer, poriferasterol, is the main component, and lesser amounts of sitosterol, α-spinasterol, 5α-stigmast-7-en-3β-ol, cholesterol, and campesterol also were detected. Flowers and fruits were found to contain a glycoside fraction in which stigmasterol, together with some sitosterol, could be detected.

TL;DR: The egg of the pales weevil contained the largest percentage of the total and individual sterols present during the entire developmental period, and the total lipid content was not correlated with the amount of sterol at the various stages of development.
Abstract: Rearing larvae of the pales weevil, Hylobius pales (Herbst), on a semi-defined diet containing known amounts of either a sterol or sterol precursor showed that a dietary source of sterol was required for growth. The optimum range of sterol content necessary for normal growth and emergence was between 0.5 and 1.0±0.05%. Diets containing both β-sitosterol and cholesterol were superior for growth and survival to diets containing either of these sterols alone or stigmasterol, ergosterol, squalene, 7-dehydrocholesterol, or lanosterol. Analysis of the larvae both from the experimental diets and from natural food (phloem of loblolly pine) showed that cholesterol, β-sitosterol, and campesterol were present in the somatic tissue in nearly all instances. The egg contained the largest percentage of the total and individual sterols present during the entire developmental period. The total lipid content was not correlated with the amount of sterol at the various stages of development.

30 Apr 1975TL;DR: In this article, the preparation of 3-oxo-pregna-4,17(20)-dien-21-carboxylic acid and esters thereof by the microbial degradation of fucosterol, cholesterol, stigmasterol, campesterol or sitosterol with Mycobacterium sp.
Abstract: The present invention is concerned with the preparation of 3-oxo-pregna-4,17(20)-dien-21-carboxylic acid and esters thereof by the microbial degradation of fucosterol, cholesterol, stigmasterol, campesterol or sitosterol with Mycobacterium sp. NRRL B-8054. The compounds of the present invention are useful antispasmodic agents and are also active against influenza virus.

TL;DR: The principal difference in sterol composition between the two species is the higher quantity of campesterol and β-sitosterol in Eriocheir sinensis in exchange for cholesterol in Cancer pagurus.

TL;DR: The presence of the two diterpenoid alcohols in coffee cell suspension cultures, would suggest that the coffee cell cultures maintain their ability to synthesize compounds unique to the parent coffee plant.
Abstract: The coffee cell cultures of Coffea arabica have been shown to contain the three sterols, β-sitosterol, stigmasterol and campesterol as the major components of the unsaponifiable fraction of the cell lipid. Two diterpe-noid alcohols, cafestol and kahweol which are major components of coffee bean oil unsaponifiables have been shown also to be present in the plant cell cultures. The presence of the two diterpenoid alcohols in coffee cell suspension cultures, would suggest that the coffee cell cultures maintain their ability to synthesize compounds unique to the parent coffee plant.
