Enterolignan

	Enterolignan Enterolignans are organic compounds formed by the action of gut microflora on lignans. They are thus the products of the combined action of both plants and of the animal gut. Prominent enterolignans are enterodiol and enterolactone Enterolactone is a organic compound classified as an enterolignan. It is formed by the action of intestinal bacteria on plant lignan precursors present in the diet. Sources Many dietary plant lignan precursors, such as secoisolariciresinol, mat .... Enterolignans are also called "mammalian lignans", although that term is self-contradictory since mammals do not produce lignans. . Enterolignans have attracted intense attention because of their potential beneficial roles in nutrition. Elevated levels of enterodiol in urine are attributed consumption of tea and other lignan-rich foods. References Polyols Lignans Phenols {{aromatic-stub ...

	Lignans The lignans are a large group of low molecular weight polyphenols found in plants, particularly seeds, whole grains, and vegetables. The name derives from the Latin word for "wood". Lignans are precursors to phytoestrogens. They may play a role as antifeedants in the defense of seeds and plants against herbivores. Biosynthesis and metabolism Lignans and lignin differ in their molecular weight, the former being small and soluble in water, the latter being high polymers that are undigestable. Both are polyphenolic substances derived by oxidative coupling of monolignols. Thus, most lignans feature a C18 cores, resulting from the dimerization of C9 precursors. The coupling of the lignols occurs at C8. Eight classes of lignans are: "furofuran, furan, dibenzylbutane, dibenzylbutyrolactone, aryltetralin, arylnaphthalene, dibenzocyclooctadiene, and dibenzylbutyrolactol." Many lignans are metabolized by mammalian gut microflora, producing so-called enterolignans. Food sources Flax se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]

	Enterolactone Enterolactone is a organic compound classified as an enterolignan. It is formed by the action of intestinal bacteria on plant lignan precursors present in the diet. Sources Many dietary plant lignan precursors, such as secoisolariciresinol, matairesinol, lariciresinol, pinoresinol, and sesamin, can be metabolized by Gut microbiota, gut microbes to enterolactone. In edible plants lignans are bound to the fiber fraction and therefore fiber-rich food products, such as cereals, vegetables, fruits and berries, are generally good sources of lignans and enterolactone. The richest known dietary sources of enterolactone precursors are flaxseed and sesame seed. Since enterolactone is produced by specific species of gut microbiota, the capacity to produce it varies between people. Antibiotic treatments can abolish the capacity to produce enterolactone. It may take up to a year before enterolactone production is restored. Health effects Enterolactone is suggested to possess beneficial hea ...

	Organic Compound In chemistry, organic compounds are generally any chemical compounds that contain carbon-hydrogen or carbon-carbon bonds. Due to carbon's ability to catenate (form chains with other carbon atoms), millions of organic compounds are known. The study of the properties, reactions, and syntheses of organic compounds comprise the discipline known as organic chemistry. For historical reasons, a few classes of carbon-containing compounds (e.g., carbonate salts and cyanide salts), along with a few other exceptions (e.g., carbon dioxide, hydrogen cyanide), are not classified as organic compounds and are considered inorganic. Other than those just named, little consensus exists among chemists on precisely which carbon-containing compounds are excluded, making any rigorous definition of an organic compound elusive. Although organic compounds make up only a small percentage of Earth's crust, they are of central importance because all known life is based on organic compounds. Living t ...

picture info	Polyols In organic chemistry, a polyol is an organic compound containing multiple hydroxyl groups (). The term "polyol" can have slightly different meanings depending on whether it is used in food science or polymer chemistry. Polyols containing two, three and four hydroxyl groups are diols, triols, and tetrols, respectively. Classification Polyols may be classified according to their chemistry. Some of these chemistries are polyether, polyester, polycarbonate and also acrylic polyols. Polyether polyols may be further subdivided and classified as polyethylene oxide or polyethylene glycol (PEG), polypropylene glycol (PPG) and Polytetrahydrofuran or PTMEG. These have 2, 3 and 4 carbons respectively per oxygen atom in the repeat unit. Polycaprolactone polyols are also commercially available. There is also an increasing trend to use biobased (and hence renewable) polyols. Uses Polyether polyols have numerous uses. As an example, polyurethane foam is a big user of polyether polyols.
