Plant sterols are structural components of cell membranes that provide rigidity, permeability, and regional identity to membranes. Sterols are also the precursors to the brassinosteroid signaling molecules. Evidence is accumulating that specific sterols have roles in pattern formation during development. COTYLEDON VASCULAR PATTERNING1 (CVP1) encodes C-24 STEROL METHYLTRANSFERASE2 (SMT2), one of...

Maize (Zea mays L.) caryopses were grown in the presence of fenpropimorph, a systemic fungicide, for 7 days in the dark. Membrane fractions enriched, respectively, in endoplasmic reticulum, plasma membrane, and mitochondria were isolated from control and treated maize roots and analyzed for their free sterol, phospholipid, and fatty acid composition. In treated plants, the intracellular distrib...

THE purpose of this communication is to report on the value of Gallogen* alone and in combination with soybean sterol in the treatment of experimentally induced atherosclerosis. Peterson and co-workers observed that the addition of soybean sterols to the diet of chicks, on a high fat-high cholesterol diet, lowers cholesterol levels in blood and liver more than when the soybean sterols were omit...

In the preceding paper (1) we have investigated the metabolic basis for the sterol requirements of insects and have provided evidence to show that in the case of the beetle Dermestes vulpinus cholesterol biogenesis is multiply blocked. While the lack of sterol synthesis seems to be a metabolic defect common to all insects, the requirements for specific sterols vary widely among insect species. ...

The discovery of an acylated steryl glucoside in plant tissue in 1964 (13) raised the number of known forms of sterols in plants to four. These are the free sterols, sterol esters, steryl glycosides, and acylated steryl glycosides. Kiribuchi et al. (12) analyzed the sterol content of soybean and found that sterol ester was present in very small amount and that the sterol was mostly in the form ...

The objective of the present study was to assess the intake of naturally occurring plant sterols and β-carotene via the overall diet of Belgian pre-school children and adults. Two different Belgian food consumption databases were used: (1) one with consumption data of pre-school children (2·5-6·5 years old) and (2) one with consumption data of adults ( ≥ 15 years old). These consumption data we...
