Sterol Ester
Sterol esters are a heterogeneous group of chemical compounds. They are created when the hydroxyl group of a sterol and a fatty acid undergo an esterification reaction. They can be found in trace amounts in every cell type but are highly enriched in foam cells and are common components of human skin oil. Plant sterol esters have been shown to reduce the level of low-density lipoprotein (LDL) cholesterol in blood when ingested. Plant sterol esters used for dietary supplements are made from phytosterols and fatty acids also derived from plants. They are added to certain oil-containing products like margarine, milk, or yogurt to make functional foods for controlling cholesterol levels. Studies have indicated that consumption of about 2 grams per day of phytosterol esters provides a reduction in LDL cholesterol of around 10%. Sterol esters are added to certain Unilever products under the brand name Becel/Flora. See also * Phytosterols * Stanol ester * Sitosterolemia Sitosterolemia ...

Chemical Compound
A chemical compound is a chemical substance composed of many identical molecules (or molecular entities) containing atoms from more than one chemical element held together by chemical bonds. A molecule consisting of atoms of only one element is therefore not a compound. A compound can be transformed into a different substance by a chemical reaction, which may involve interactions with other substances. In this process, bonds between atoms may be broken and/or new bonds formed. There are four major types of compounds, distinguished by how the constituent atoms are bonded together. Molecular compounds are held together by covalent bonds; ionic compounds are held together by ionic bonds; intermetallic compounds are held together by metallic bonds; coordination complexes are held together by coordinate covalent bonds. Non-stoichiometric compounds form a disputed marginal case. A chemical formula specifies the number of atoms of each element in a compound molecule, using the s ...

Margarine
Margarine (, also , ) is a spread used for flavoring, baking, and cooking. It is most often used as a substitute for butter. Although originally made from animal fats, most margarine consumed today is made from vegetable oil. The spread was originally named ''oleomargarine'' from Latin for ''oleum'' (olive oil) and Greek ''margarite'' ("pearl", indicating luster). The name was later shortened to ''margarine''. Margarine consists of a water-in-fat emulsion, with tiny droplets of water dispersed uniformly throughout a fat phase in a stable solid form. While butter is made by concentrating the butterfat of milk through agitation, modern margarine is made through a more intensive processing of refined vegetable oil and water. Per federal regulation, margarine must have a minimum fat content of 80 percent (with a maximum of 16% water) to be labeled as such in the United States, although the term is used informally to describe vegetable-oil-based spreads with lower fat content.

Sitosterolemia
Sitosterolemia is a rare autosomal recessively inherited lipid metabolic disorder. It is characterized by hyperabsorption and decreased biliary excretion of dietary sterols (including the plant phytosterol beta-sitosterol). Healthy persons absorb only about 5% of dietary plant sterols, but sitosterolemia patients absorb 15% to 60% of ingested sitosterol without excreting much into the bile. The phytosterol campesterol is more readily absorbed than sitosterol. Sitosterolemia patients develop hypercholesterolemia, tendon and tuberous xanthomas, premature development of atherosclerosis, and abnormal hematologic and liver function test results. Signs and symptoms Sitosterolemia may share several clinical characteristics with the well-characterized familial hypercholesterolemia (FH), such as the development of tendon xanthomas in the first 10 years of life and the development of premature atherosclerosis. However, in contrast to FH patients, sitosterolemia patients usually have nor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stanol Ester
Stanol esters is a heterogeneous group of chemical compounds known to reduce the level of low-density lipoprotein (LDL) cholesterol in blood when ingested, though to a much lesser degree than prescription drugs such as statins. The starting material is phytosterols from plants. These are first hydrogenated to give a plant stanol which is then esterified with a mixture of fatty acids also derived from plants. Plant stanol esters are found naturally occurring in small quantities in fruits, vegetables, nuts, seeds, cereals, legumes, and vegetable oils. Stanol ester is often added to rapeseed oil based margarine or other foods for its health benefits. Studies have indicated that consumption of about 2-3 grams per day provides a reduction in LDL cholesterol of about 10-15%. The compound itself passes through the gut, with very little entering the blood stream or lymph. Its presence in the gut, however, reduces both the amount of cholesterol the body absorbs from food and the rea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phytosterols
Phytosterols are phytosteroids, similar to cholesterol, that serve as structural components of biological membranes of plants. They encompass plant sterols and stanols. More than 250 sterols and related compounds have been identified. Free phytosterols extracted from oils are insoluble in water, relatively insoluble in oil, and soluble in alcohols. Phytosterol-enriched foods and dietary supplements have been marketed for decades. Despite well-documented LDL cholesterol-lowering effects from long-term consumption of phytosterols, there is insufficient evidence for an effect on cardiovascular diseases, fasting blood sugar, glycated hemoglobin, or overall mortality rate. Structure They have a fused polycyclic structure and vary in carbon side chains and / or presence or absence of a double bond (saturation). They are divided into 4,4-dimethyl phytosterols, 4-monomethyl phytosterols, and 4-desmethyl phytosterols based on the location of methyl groups at the carbon-4 position. Sta ...

Becel
Becel is a brand of vegetable oil spread produced by Upfield. In France it is sold as Fruit D'or in the United States as Promise. The name ''Becel'' originates from the initials BCL (Blood Cholesterol-Lowering). When introduced, the makers of Becel claimed to achieve a blood cholesterol lowering effect by modifying the triacylglycerol (TAG) profile of the fat used in the margarine under the idea that an increased level of polyunsaturated fatty acids (PUFA) reduces the blood cholesterol level. More recently, products were introduced under the "Pro-active" sub-brand. These products are based on the effects of plant sterols and sterol esters lowering blood cholesterol. This is achieved by a highly increased resorption of beta-sitosterol and other phytosterols which accumulate especially in the intima of blood vessels and may cause arteriosclerotic plaques. In consequence, Consumption of Becel products does not lower the risk for coronary diseases such as arteriosclerosis and there ...

Functional Food
A functional food is a food claimed to have an additional (often one related to health promotion or disease prevention) by adding new ingredients or more of existing ingredients. The term may also apply to traits purposely bred into existing edible plants, such as purple or gold potatoes having increased anthocyanin or carotenoid contents, respectively. Functional foods may be "designed to have physiological benefits and/or reduce the risk of chronic disease beyond basic nutritional functions, and may be similar in appearance to conventional food and consumed as part of a regular diet". The term was first used in the 1980s in Japan, where there is a government approval process for functional foods called Foods for Specified Health Use (FOSHU). Industry The functional food industry, consisting of food, beverage and supplement sectors, is one of the several areas of the food industry that is experiencing fast growth in recent years.Roberts, W.

Yogurt
Yogurt (; , from tr, yoğurt, also spelled yoghurt, yogourt or yoghourt) is a food produced by bacterial Fermentation (food), fermentation of milk. The bacteria used to make yogurt are known as ''yogurt cultures''. Fermentation of sugars in the milk by these bacteria produces lactic acid, which acts on milk protein to give yogurt its texture (food), texture and characteristic tart flavor. Cow's milk is the milk most commonly used to make yogurt. Milk from water buffalo, goats, sheep, ewes, mares, camels, and yaks are also used to produce yogurt. The milk used may be Milk#Creaming and homogenization, homogenized or not. It may be pasteurized or raw milk, raw. Each type of milk produces substantially different results. Yogurt is produced using a culture of Lactobacillus delbrueckii subsp. bulgaricus, ''Lactobacillus delbrueckii'' subsp. ''bulgaricus'' and ''Streptococcus thermophilus'' bacteria. In addition, other Lactobacillus, lactobacilli and Bifidobacterium, bifidobacteria a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Milk
Milk is a white liquid food produced by the mammary glands of mammals. It is the primary source of nutrition for young mammals (including breastfed human infants) before they are able to digestion, digest solid food. Immune factors and immune-modulating components in milk contribute to milk immunity. Early-lactation milk, which is called colostrum, contains antibody, antibodies that strengthen the immune system, and thus reduces the risk of many diseases. Milk contains many nutrients, including protein and lactose. As an agricultural product, dairy milk is Milking, collected from farm animals. In 2011, Dairy farming, dairy farms produced around of milk from 260 million dairy cows. India is the world's largest producer of milk and the leading exporter of skimmed milk powder, but it exports few other milk products. Because there is an ever-increasing demand for dairy products within India, it could eventually become a net importer of dairy products. New Zealand, Germany and the ...

Hydroxyl Group
In chemistry, a hydroxy or hydroxyl group is a functional group with the chemical formula and composed of one oxygen atom covalently bonded to one hydrogen atom. In organic chemistry, alcohols and carboxylic acids contain one or more hydroxy groups. Both the negatively charged anion , called hydroxide, and the neutral radical , known as the hydroxyl radical, consist of an unbonded hydroxy group. According to IUPAC definitions, the term ''hydroxyl'' refers to the hydroxyl radical () only, while the functional group is called a ''hydroxy group''. Properties Water, alcohols, carboxylic acids, and many other hydroxy-containing compounds can be readily deprotonated due to a large difference between the electronegativity of oxygen (3.5) and that of hydrogen (2.1). Hydroxy-containing compounds engage in intermolecular hydrogen bonding increasing the electrostatic attraction between molecules and thus to higher boiling and melting points than found for compounds that lack this func ...
