What type of lipid is stigmasterol?
Stigmasterol, a Soy Lipid–Derived Phytosterol, Is an Antagonist of the Bile Acid Nuclear Receptor FXR | Pediatric Research.
What is the source of stigmasterol?
Stigmasterol is found in the fats and oils of soybean, calabar bean and rape seed, as well as several other vegetables, legumes, nuts, seeds, and unpasteurized milk.
What is the use of stigmasterol?
Sterols are used in the manufacture of pharmaceuticals. Stigmasterol from soybean oil is used in the manufacture of progesterone and corticoids, whereas β-sitosterol is used to produce estrogens, contraceptives, diuretics, and male hormones (28).
Is stigmasterol a lipid?
The main sterol in animal lipids is cholesterol, whereas plant sterols or phytosterols include campersterol, stigmasterol, and sitosterol.
What is stigmasterol and Campesterol?
The plant sterol pathway leading to stigmasterol. Plants produce a mixture of sterols, campesterol (24-methyl) and sitosterol and stigmasterol (24-ethyl sterols). Stigmasterol is derived from sitosterol by the action of sterol C-22 desaturases. Campesterol is the preferred precursor of brassinosteroids (BR).
Is stigmasterol water soluble?
Stigmasterol is a phytosterol, meaning it is steroid derived from plants. ,It is very hydrophobic, practically insoluble in water, and relatively neutral. Stigmasterol is among the most abundant of plant sterols with its major function being to maintain the structure and physiology of cell membranes.
What is Campesterol and stigmasterol?
Plants produce a mixture of sterols, campesterol (24-methyl) and sitosterol and stigmasterol (24-ethyl sterols). Stigmasterol is derived from sitosterol by the action of sterol C-22 desaturases. Campesterol is the preferred precursor of brassinosteroids (BR).
Who discovered stigmasterol?
Rosalind Wulzen
Discovery. Once called Wulzen factor in the mid-20th century, stigmasterol was discovered by the University of California physiologist Rosalind Wulzen (born 1886).
What is Campesterol used for?
Campesterol is a phytosterol, meaning it is a steroid derived from plants. As a food additive, phytosterols have cholesterol-lowering properties (reducing cholesterol absorption in intestines), and may act in cancer prevention.
Is stigmasterol polar?
In short, stigmasterol was identified as the major non-polar component from these two plant extracts.
Why do plants convert sitosterol to stigmasterol?
The composition of free sterols and sterol conjugates influences the liquid-ordered phase formation (Grosjean et al., 2015). Stigmasterol by itself lacks the ability to increase membrane order, whereas sitosterol and campesterol increase the order.
What does high Campesterol mean?
High campesterol and beta-sitosterol indicate cholesterol overabsorption. Associated with higher LDL-C and increased CVD risk. May be associated with tendon xanthomas, premature CVD and phytosterolemia if values are very high3.
How much Stigmasterol is needed to lower LDL cholesterol?
Consumption of 2 grams per day of plant sterols is associated with a reduction in blood LDL cholesterol of 8–10%, possibly lowering cardiovascular disease risk. As a factor in cellular processes of plants, stigmasterol may have roles in plant stress responses, metabolism, and enzymes involved in biosynthesis of plant cell membranes.
What kind of plant is stigmasterol found in?
Stigmasterol is an unsaturated phytosterol occurring in the plant fats or oils of numerous plants, such as soybean, calabar bean, and rape seed, and in herbs used in herbalism practices, including the Chinese herbs Ophiopogon japonicus (Mai men dong), in Mirabilis jalapa.
Where can I find stigmasterol in my diet?
Stigmasterol is found in the fats and oils of soybean, calabar bean and rape seed, as well as several other vegetables, legumes, nuts, seeds, and unpasteurized milk. Stigmasterol is a 3beta-sterol that consists of 3beta-hydroxystigmastane having double bonds at the 5,6- and 22,23-positions. It has a role as a vitamin and a plant metabolite.
What kind of effects does stigmasterol have on the body?
Stigmasterol has also been shown to exert anti-angiogenic and anti-cancer effects via the downregulation of TNF-alpha and VEGFR-2. Being a steroid, stigmasterol is precursor of anabolic steroid boldenone.
