The current paper reviews the content and variation of fiber fractions in feed ingredients commonly used in swine diets. Carbohydrates serve as the main source of energy in diets fed to pigs. Carbohydrates may be classified according to their degree of polymerization: monosaccharides, disaccharides, oligosaccharides, and polysaccharides.

Carbohydrates are within the four major classes of biomolecules along with proteins, lipids and nucleic acids.
A reducing sugar is any sugar that is capable of acting as a reducing agent because it has a free aldehyde group or a free ketone group. The monosaccharides can be divided into two groups: the aldoses , which have an aldehyde group, and the ketoses , which have a ketone group. Ketoses must first tautomerize to aldoses before they can act as reducing sugars. The common dietary monosaccharides galactose , glucose and fructose are all reducing sugars. Disaccharides are formed from two monosaccharides and can be classified as either reducing or nonreducing. Nonreducing disaccharides like sucrose and trehalose have glycosidic bonds between their anomeric carbons and thus cannot convert to an open-chain form with an aldehyde group; they are stuck in the cyclic form.
Structures and characteristics of carbohydrates in diets fed to pigs: a review
Most people are familiar with carbohydrates, one type of macromolecule, especially when it comes to what we eat. Carbohydrates are, in fact, an essential part of our diet; grains, fruits, and vegetables are all natural sources of carbohydrates. Carbohydrates provide energy to the body, particularly through glucose, a simple sugar that is a component of starch and an ingredient in many staple foods. Carbohydrates also have other important functions in humans, animals, and plants. Carbohydrates can be represented by the stoichiometric formula CH 2 O n , where n is the number of carbons in the molecule.
Monosaccharides such as glucose and fructose are crystalline solids at room temperature, but they are quite soluble in water, each molecule having several OH groups that readily engage in hydrogen bonding. The chemical behavior of these monosaccharides is likewise determined by their functional groups. An important reaction of monosaccharides is the oxidation of the aldehyde group, one of the most easily oxidized organic functional groups. These reactions have been used as simple and rapid diagnostic tests for the presence of glucose in blood or urine. Monosaccharides are crystalline solids at room temperature and quite soluble in water.
Analysis of Carbohydrates by Capillary Electrophoresis pp Cite as. This early definition has been widened to any multifunctional compounds containing a number of hydroxyl groups of similar reactivity and at least one asymmetric carbon atom. Consequently, a number of examples exist that have very different molecular formulas but are nevertheless due to their chemical reactivity carbohydrates, for example deoxysugars or aminosugars.

16.6: Properties of Monosaccharides
Metrics details. The current paper reviews the content and variation of fiber fractions in feed ingredients commonly used in swine diets. Carbohydrates serve as the main source of energy in diets fed to pigs. Carbohydrates may be classified according to their degree of polymerization: monosaccharides, disaccharides, oligosaccharides, and polysaccharides. Digestible carbohydrates include sugars, digestible starch, and glycogen that may be digested by enzymes secreted in the gastrointestinal tract of the pig.
Structures and properties of carbohydrates
Saccharides are better known as carbohydrates literally hydrates of carbon. Relatively complex carboyhydrates are known as polysaccharides. The simplest carbohydrates are monosaccharides, which are small straight-chain aldehydes and ketones with many hydroxyl groups added, usually one on each carbon except the functional group.
Chemically synthesised sugars or sugar derivatives are classified in C07H. Obtaining or extracting cellulose for the purpose of making paper is classified in D21C. With only 3 carbon atoms, glyceraldehyde is the simplest of all aldoses. Aldoses isomerise to ketoses in the Lobry-de Bruyn-van Ekenstein transformation.
Properties of monosaccharide. Monosaccharide disaccharide and polysaccharide with free anomeric carbon is called the reducing end. The.
Но общественные организации типа Фонда электронных границ считали. И развязали против Стратмора непримиримую войну. ГЛАВА 24 Дэвид Беккер стоял в телефонной будке на противоположной стороне улицы, прямо напротив городской больницы, откуда его только что выставили за причинение беспокойства пациенту под номером 104, месье Клушару. Все внезапно осложнилось, пошло совсем не так, как он рассчитывал. Мелкая любезность, которую он оказал Стратмору, забрав личные вещи Танкадо, вылилась в поиски таинственного кольца, как в известной игре, где нужно находить спрятанные предметы.
Забавно, - сказала. - Последний файл из намеченных на вчера был загружен в одиннадцать сорок. - И. - Итак, ТРАНСТЕКСТ вскрывает один шифр в среднем за шесть минут. Последний файл обычно попадает в машину около полуночи. И не похоже, что… - Что? - Бринкерхофф даже подпрыгнул.
Вы не шутите. - Если бы я шутил… Я поставил его вчера в одиннадцать тридцать вечера. Шифр до сих пор не взломан. Сьюзан от изумления застыла с открытым ртом. Она посмотрела на часы, потом на Стратмора. - Все еще не взломан.
