Chemical and Physical Properties of Polysaccharides in Cooking
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.
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. Non-digestible carbohydrates, also known as fiber, may be fermented by microbial populations along the gastrointestinal tract to synthesize short-chain fatty acids that may be absorbed and metabolized by the pig. These non-digestible carbohydrates include two disaccharides, oligosaccharides, resistant starch, and non-starch polysaccharides. The concentration and structure of non-digestible carbohydrates in diets fed to pigs depend on the type of feed ingredients that are included in the mixed diet.
16.6: Properties of Monosaccharides
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. Monosaccharides are the building blocks of disaccharides such as sucrose and lactose and polysaccharides such as cellulose and starch. A disaccharide is formed when two monosaccharides simple sugars undergo a condensation reaction which involves the elimination of a small molecule, such as water, from the functional groups only.

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. Monosaccharides are quite soluble in water because of the numerous OH groups that readily engage in hydrogen bonding with water.
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.
Concept Review Exercises
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. In other words, the ratio of carbon to hydrogen to oxygen is in carbohydrate molecules.

Хейл находился всего в метре от нее, когда она встала и преградила ему дорогу. Его массивная фигура буквально нависла над ней, запах одеколона ударил в ноздри. - Я сказала. - Она смотрела ему прямо в .
Не понимаю, - сказала. - Мы же говорим не о реверсии какой-либо сложной функции, а о грубой силе. PGP, Lucifer, DSA - не важно. Алгоритм создает шифр, который кажется абсолютно стойким, а ТРАНСТЕКСТ перебирает все варианты, пока не находит ключ. Стратмор ответил ей тоном учителя, терпеливого и умеющего держать себя в руках: - Да, Сьюзан, ТРАНСТЕКСТ всегда найдет шифр, каким бы длинным он ни .
Он был крупнее, чем ожидал Беккер. Волосатая грудь начиналась сразу под тройным подбородком и выпячивалась ничуть не меньше, чем живот необъятного размера, на котором едва сходился пояс купального халата с фирменным знаком отеля. Беккер старался придать своему лицу как можно более угрожающее выражение. - Ваше имя. Красное лицо немца исказилось от страха.
