Plant sterols and atherosclerosis

Current Opinion in Lipidology, 2013
Plant sterols as ingredients to functional foods are recommended for lowering LDL cholesterol. However, there is an ongoing discussion whether the use of plant sterols is safe.Genetic analyses showed that common variants of the ATP binding cassette transporter G8 (ABCG8) and ABO genes are associated with elevated circulating plant sterols and higher ...

Cholesterol-lowering effect of plant sterols

Current Atherosclerosis Reports, 2008
Plant sterols are plant components that have a chemical structure similar to cholesterol except for the addition of an extra methyl or ethyl group; however, plant sterol absorption in humans is considerably less than that of cholesterol. In fact, plant sterols reduce cholesterol absorption and thus reduce circulating levels of cholesterol.

Metabolism of plant sterols by nematodes

Lipids, 1991
AbstractParasitic nematodes do not biosynthesize sterolsde novo and therefore possess a nutritional requirement for sterol, which must be obtained from their hosts. Consequently, the metabolism of phytosterols by plant‐parasitic nematodes is an important process with potential for selective exploitation.

Dietary Plant Sterols and Cholesterol Metabolism

Nutrition Reviews, 2007
Plant sterols, naturally occurring in foods of plant origin, reduce cholesterol absorption. Experimental studies show plant sterols to be an important part of the serum-cholesterol lowering effect of certain diets and dietary components. Epidemiological data show that individuals with higher intakes of plant sterols from their habitual diets have lower

Plant Sterol Biosynthesis: Identification and Characterization of Higher Plant Δ7-Sterol C5(6)-Desaturase

Archives of Biochemistry and Biophysics, 1996
Microsomes obtained from maize seedlings catalyzed the introduction of the delta5-bond into delta7-sterols to yield the corresponding delta 5,7-sterols. Enzymatic bioassay conditions have been developed for the first time for delta 7-sterol C5(6)-desaturase in photosynthetic organisms.

Plant Sterol Diversity in Pollen from Angiosperms

Lipids, 2015
AbstractHere we have examined the composition of free sterols and steryl esters of pollen from selected angiosperm species, as a first step towards a comprehensive analysis of sterol biogenesis in the male gametophyte. We detected four major sterol structural groups: cycloartenol derivatives bearing a 9β,19‐cyclopropyl group, sterols with a double bond

Plant Sterols and Stanols

2005
The expanding market of 'functional foods' containing plant sterols and stanols has focused interest on their cholesterol-lowering effects as well on possible adverse effects. Trials of cholesterol lowering demonstrate that intake of 2 g/day of plant sterols and stanols reduces serum low-density lipoprotein (LDL) cholesterol concentrations by ...
