A carbohydrate is an organic compound that consists only of carbon, hydrogen, and oxygen, usually with a hydrogen:oxygen atom ratio of 2:1 (as in water); in other words, with the empirical formula Cm(H2O)n. The carbohydrates (saccharine) are divided Into four chemical groupings: incarcerations, disaccharide, electrocardiographs, and polysaccharides. In general, the incarcerations and disaccharide, which are smaller (lower molecular weight) carbohydrates, are commonly referred to as sugars. 2)industrial application of cellulose :- The Kraft process is used to separate cellulose from logging, another major component f plant matter.

Cellulose is the major constituent of paper, paperboard, and card stock and of textiles made from cotton, linen, and other plant fibers. Cellulose can be converted Into cellophane, a thin transparent film, and Into rayon, an important fiber that has been used for textiles since the beginning of the 20th century. Both cellophane and rayon are known as “regenerated cellulose fibers”; they are Identical to cellulose In chemical structure and are usually made from dissolving pulp Vial viscose. A more recent and environmentally friendly method to produce a form of anon is the Loosely process.

Cellulose is the raw material in the manufacture of nitrocellulose (cellulose nitrate) which is used in smokeless gunpowder and as the base material for celluloid used for photographic and movie films until the mid-sass. Cellulose is used to make water-soluble adhesives and binders such as methyl cellulose and carbohydrates cellulose which are used in wallpaper paste. Microelectronics cellulose (Iii) and powdered cellulose (Iii) are used as inactive fillers in tablets[14] and as thickeners and stabilizers In processed foods.

Cellulose odder Is for example used in Karat’s Parmesan cheese to prevent caking Inside the tube. Cellulose Is used In the laboratory as a stationary phase for thin layer chromatography. Cellulose fibers are also used In liquid filtration, sometimes In combination with diatomaceous earth or other filtration media, to create a filter bed of inert material. Cellulose is further used to make hydrophilic and highly absorbent sponges. Cellulose insulation made from recycled paper is becoming popular as an environmentally preferable material for building insulation. It can be treated with boric acid as a fire retardant.

Cellulose consists of crystalline and amorphous regions. By treating it with strong acid, the amorphous regions can be broken up, thereby producing incontestable cellulose, a novel material with many desirable properties. [1 5] Recently, incontestable cellulose was used as the filler phase in based polymer matrices to produce incompetents with superior thermal and mechanical properties 3) The Hofmann rearrangement Is the organic reaction of a primary amide to a primary amine with one fewer carbon [pick reaction is also sometimes called the Hofmann degradation or the Harmon Process

The reaction of bromine with sodium hydroxide forms sodium hypocrite in situ, which transforms the primary amide into an intermediate confiscate. The intermediate confiscate is hydrolysis to a primary amine, giving off carbon dioxide. [pick] Hydrolysis[edit] In its most characteristic reaction, APPC reacts upon contact with water to release hydrogen chloride and give phosphorus oxides.

The first hydrolysis product is phosphorus chloride: APPC + H2O -+ POOCH + CLC In hot water, hydrolysis proceeds completely to Roth-phosphoric acid: APPC + AH -+ HAPPY + CLC ) Solid phosphorus(V) chloride (phosphorus phenolphthalein) reacts violently with alcohols at room temperature, producing clouds of hydrogen chloride c) Phosphorus(V) chloride is a solid which reacts with carboxylic acids in the cold to give steamy acidic fumes of hydrogen chloride. It leaves a liquid mixture of the call chloride and a phosphorus compound, phosphorus tetrachloride oxide (phosphorus chloride) – POOCH.

The call chloride can be separated by fractional distillation. For example: d) Leaderless and stones react with phosphorus phenolphthalein to give seminal- dichloride (CB. Conical) compounds. The oxygen atom in the carbonyl group is replaced by two chlorine atoms. Allayed COACH + APPC [opt]CHICHI + POOCH stereophonic + APPC [opt]CHICHI’S + POOCH pyramidal and pyridoxine. It is based on a pyridine ring, with hydroxyl, methyl, and hydrothermal subsistent. It is converted to the biologically active form pyramidal 5- phosphate.

Vitamin 86 assists in the balancing of sodium and potassium as well as promoting red blood cell production. [citation needed] It is linked to cardiovascular health by decreasing the formation of homogeneity. Pyridoxine may help balance Ramona changes in women and aid the immune system. [2] Lack of pyridoxine may cause anemia, nerve damage, seizures, skin problems, and sores in the mouth. [3] It is required for the production of the nominee neurotransmitters serotonin, dopamine, morphogenesis and epinephrine, as it is the precursor to pyramidal phosphate: cofactor for the enzyme aromatic amino acid destroyable.

This enzyme is responsible for converting the precursors 5-hydrotherapy’s (5-HTTP) into serotonin and leopard (L-DOPE) into dopamine, noradrenalin and adrenaline. As such it has been implicated in the treatment of depression and anxiety I Pyridoxine[l ] II-PACK name[hide] 4,5-Ibis(hydrothermal)-2-nitroglycerin-3-OLL I l[Pick] 6) Glucose (ugly:kooks/ or /-kook/; C6H1206, also known as C)-glucose, dextrose, or grape sugar) is a simple macroeconomics found in plants.

It is one of the three dietary incarcerations, along with fructose and gallstones, that are absorbed directly into the bloodstream during digestion[pick] Conversion of glucose [pick]kooks like: heath commiseration of glucose to fructose is part of the glycoside cycle that converts glucose to private. The way this is done is to isomerism the allayed (hemispherical) loose to the ketene (as a hemispherical) fructose,and make another phosphate ester. The commiseration takes advantage of the ease of breakage of a C-H bond which involves a carbon next to a carbonyl carbon.

This is important in the next step which cleaves the bond between carbons three and four of fructose. It is noted that this bond involves the carbon next to the carbonyl carbon of fructose. This cleavage would not have been possible without the commiseration of glucose to fructose, because the carbonyl group of glucose is too far from carbons three and four to make hat bond breakable. To make that bond breakable. The pinnacle rearrangement or pinnacle-pinochle rearrangement is a method for converting a 1,2-idol to a carbonyl compound in organic chemistry.

This 1,2- rearrangement takes place under acidic conditions. The name of the reaction comes from the rearrangement of pinnacle to pinochle. In the course of this organic reaction, propagation of one of the -OH groups occurs and a carbonation is formed. If both the -OH groups are not alike, then the one which yields a more stable carbonation participates in the reaction. Subsequently, an alkyl roof from the adjacent carbon migrates to the carbonation center.

The driving force for this rearrangement step is believed to be the relative stability of the resultant osmium ion, which has complete octet configuration at all centers (as opposed to the preceding carbonation). The migration of alkyl groups in this reaction occurs in accordance with their usual migratory aptitude, I. E. Aryl >>>> hydride > Phenyl > tertiary carbonation (if formed by migration) > secondary carbonation (if formed by migration) > methyl cationic . The conclusion which group stabilizes carbonation more effectively is migrated
