Pentosan Polysulphate
Pentosans are polymers composed of pentoses. In contrast to cellulose, which is composed of hexose (glucose) monomers, pentosans are derived from five-carbon sugars such as xylose. Pentosan-rich biomass is the precursor to furfural. The pentosan content has been determined for many natural materials: *29-25%: oat hulls, cottonseed hulls, barley, sugarcane bagasse, sunflower husks *24-20% wheat straw, flax shives, hazelnut shells, birchwood, eucalyptus wood *8% pinewood *3% peanut shells Pentosans can act as heparinoids, glycosaminoglycans which are derivatives of heparin. They can have an influence on bread quality.Water-Soluble Pentosans in Flours Varying Widely in Bread-Making Potential.

Polymer
A polymer () is a chemical substance, substance or material that consists of very large molecules, or macromolecules, that are constituted by many repeat unit, repeating subunits derived from one or more species of monomers. Due to their broad spectrum of properties, both synthetic and natural polymers play essential and ubiquitous roles in everyday life. Polymers range from familiar synthetic plastics such as polystyrene to natural biopolymers such as DNA and proteins that are fundamental to biological structure and function. Polymers, both natural and synthetic, are created via polymerization of many small molecules, known as monomers. Their consequently large molecular mass, relative to small molecule compound (chemistry), compounds, produces unique physical property, physical properties including toughness, high rubber elasticity, elasticity, viscoelasticity, and a tendency to form Amorphous solid, amorphous and crystallization of polymers, semicrystalline structures rath ...

Hazelnut
The hazelnut is the fruit of the hazel tree and therefore includes any of the nuts deriving from species of the genus '' Corylus'', especially the nuts of the species ''Corylus avellana''. They are also known as cobnuts or filberts according to species. Hazelnuts are used as a snack food, in baking and desserts, and in breakfast cereals such as muesli. In confectionery, they are used to make praline, and also used in combination with chocolate for chocolate truffles and products such as chocolate bars and hazelnut cocoa spreads such as Nutella. They are also used in Frangelico liqueur. Hazelnut oil, pressed from hazelnuts, is strongly flavored and high in monounsaturated fat. It is used as a cooking oil and as a salad or vegetable dressing. Turkey is the world's largest producer of hazelnuts, accounting for 58% of total production in 2023. Description A hazelnut cob is roughly spherical to oval, about long and in diameter, with an outer fibrous husk surrounding a sm ...

Interstitial Cystitis
Interstitial cystitis (IC), a type of bladder pain syndrome (BPS), is chronic pain in the Urinary bladder, bladder and pelvic floor of unknown cause. Symptoms include urinary urgency, feeling the need to urinate right away, urinary frequency, needing to urinate often, bladder pain (pain in the organ) and pain with sex. IC/BPS is associated with depression (mood), depression and lower quality of life. Some of those affected also have irritable bowel syndrome and fibromyalgia. The cause of interstitial cystitis is unknown. While it can, it does not typically run in a family. The diagnosis is usually based on the symptoms diagnosis of exclusion, after ruling out other conditions. Typically the urine culture is negative. Ulceration or inflammation may be seen on cystoscopy. Other conditions which can produce similar symptoms include overactive bladder syndrome, overactive bladder, urinary tract infection (UTI), sexually transmitted infections, prostatitis, endometriosis in females ...

Thrombi
A thrombus ( thrombi) is a solid or semisolid aggregate from constituents of the blood (platelets, fibrin, red blood cells, white blood cells) within the circulatory system during life. A blood clot is the final product of the blood coagulation step in hemostasis in or out of the circulatory system. There are two components to a thrombus: aggregated platelets and red blood cells that form a plug, and a mesh of cross-linked fibrin protein. The substance making up a thrombus is sometimes called cruor. A thrombus is a healthy response to injury intended to stop and prevent further bleeding, but can be harmful in thrombosis, when a clot obstructs blood flow through a healthy blood vessel in the circulatory system. In the microcirculation consisting of the very small and smallest blood vessels the capillaries, tiny thrombi known as microclots can obstruct the flow of blood in the capillaries. This can cause a number of problems particularly affecting the alveoli in the lungs of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Xylan
Xylan (; ) ( CAS number: 9014-63-5) is a type of hemicellulose, a polysaccharide consisting mainly of xylose residues. It is found in plants, in the secondary cell walls of dicots and all cell walls of grasses. Xylan is the third most abundant polysaccharide on Earth, after cellulose and chitin. Composition Xylans are polysaccharides made up of β-1,4-linked xylose (a pentose sugar) residues with side branches of α-arabinofuranose and/or α-glucuronic acids. On the basis of substituted groups xylan can be categorized into three classes i) glucuronoxylan (GX) ii) neutral arabinoxylan (AX) and iii) glucuronoarabinoxylan (GAX). In some cases contribute to cross-linking of cellulose microfibrils and lignin through ferulic acid residues. Occurrence Plant cell structure Xylans play an important role in the integrity of the plant cell wall and increase cell wall recalcitrance to enzymatic digestion; thus, they help plants to defend against herbivores and pathogens (b ...

Bread
Bread is a baked food product made from water, flour, and often yeast. It is a staple food across the world, particularly in Europe and the Middle East. Throughout recorded history and around the world, it has been an important part of many cultures' diets. It is one of the oldest human-made foods, having been of significance since the dawn of Agriculture#History, agriculture, and plays an essential role in both religious rituals and secular culture. Bread may be Leavening agent, leavened by naturally occurring microbes (e.g. sourdough), chemicals (e.g. baking soda), industrially produced Baker's yeast, yeast, or high-pressure aeration, which creates the gas bubbles that fluff up bread. Bread may also be Unleavened bread, unleavened. In many countries, mass-produced bread often contains Food additive, additives to improve flavor, texture, color, shelf life, nutrition, and ease of production.

Heparin
Heparin, also known as unfractionated heparin (UFH), is a medication and naturally occurring glycosaminoglycan. Heparin is a blood anticoagulant that increases the activity of antithrombin. It is used in the treatment of myocardial infarction, heart attacks and unstable angina. It can be given intravenously or by subcutaneous injection, injection under the skin. Its anticoagulant properties make it useful to prevent blood clotting in blood specimen test tubes and kidney dialysis machines. Common side effects include bleeding, pain at the injection site, and thrombocytopenia, low blood platelets. Serious side effects include heparin-induced thrombocytopenia. Greater care is needed in those with poor kidney function. Heparin is contraindicated for suspected cases of Post-vaccination embolic and thrombotic events, vaccine-induced pro-thrombotic immune thrombocytopenia (VIPIT) secondary to SARS-CoV-2 vaccination, as heparin may further increase the risk of bleeding in an anti-PF4 ...

Glycosaminoglycan
Glycosaminoglycans (GAGs) or mucopolysaccharides are long, linear polysaccharides consisting of repeating disaccharide units (i.e. two-sugar units). The repeating two-sugar unit consists of a uronic sugar and an amino sugar, except in the case of the sulfated glycosaminoglycan keratan, where, in place of the uronic sugar there is a galactose unit. GAGs are found in vertebrates, invertebrates and bacteria. Because GAGs are highly polar molecules and attract water; the body uses them as lubricants or shock absorbers. Mucopolysaccharidoses are a group of metabolic disorders in which abnormal accumulations of glycosaminoglycans occur due to enzyme deficiencies. Production Glycosaminoglycans vary greatly in molecular mass, disaccharide structure, and sulfation. This is because GAG synthesis is not template driven, as are proteins or nucleic acids, but constantly altered by processing enzymes. GAGs are classified into four groups, based on their core disaccharide structures: # H ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heparinoid
Heparinoids are glycosaminoglycans which are chemically and pharmacologically related to heparin. They include oligosaccharides and sulfated polysaccharides of plant, animal, or synthetic origin. Multiple scientific studies have been conducted on heparinoids. Heparinoids, like heparin, act by interacting with heparin binding proteins, generally through ionic interactions or hydrogen bonding. Some examples of heparin binding proteins include antithrombin III. It is thought that much protein interaction with heparin is not direct, and instead heparin binding protein actually interact with glycosaminoglycan (GAG) side chains or mucins bound to the heparin polymer, so it is possible that heparinoids interact with these proteins in a similar way, acquiring GAG side chains in vivo. One counterexample is the protein chymase, which directly binds to heparin. Sulfated polysaccharides From animal tissues Dermatan sulfate is one example of a compound that is classified as a heparinoid. I ...

Peanut
The peanut (''Arachis hypogaea''), also known as the groundnut, goober (US), goober pea, pindar (US) or monkey nut (UK), is a legume crop grown mainly for its edible seeds. It is widely grown in the tropics and subtropics by small and large commercial producers, both as a grain legume and as an oil crop. Atypically among legumes, peanut pods geocarpy, develop underground; this led botanist Carl Linnaeus to name peanuts ''hypogaea'', which means "under the earth". The peanut belongs to the botanical family Fabaceae (or Leguminosae), commonly known as the legume, bean, or pea family. Like most other legumes, peanuts harbor symbiotic nitrogen-fixing bacteria in root nodules, which improve soil fertility, making them valuable in crop rotations. Despite not meeting the Botanical nut, botanical definition of a nut as "a fruit whose ovary (botany), ovary wall becomes hard at maturity," peanuts are usually categorized as nuts for culinary purposes and in common English.
