Carbohydrate

From Wikipedia, the cost-free encyclopedia

LactoseВ is aВ disaccharideВ found inВ milk. It consists of a molecule ofВ D-galactoseВ and a molecule ofВ D-glucosebonded by beta-1-4В glycosidic addition. It has a mixture of C12H22O11. AВ carbohydrateВ is a largeВ biological molecule, orВ macromolecule, consisting ofВ carbonВ (C), В hydrogenВ (H), andВ oxygenВ (O) atoms, usually with a hydrogen: oxygenВ atomВ ratio of two: 1 (as inВ water); basically, with theВ empirical formulaВ Cm(H2O)n(whereВ mВ could vary fromВ n).[1]В Some exclusions exist; for instance , В deoxyribose, a sugar element ofВ DNA, WEB PAGE LINK " http://en.wikipedia.org/wiki/Carbohydrate" \l " cite_note-2" [2]В has the empirical formula C5H10O4.[3]В Carbohydrates are technicallyВ hydratesВ of carbon;[4]В structurally it is more accurate to look at them asВ polyhydroxy aldehydesВ andВ ketones.[5]The term is quite common inВ biochemistry, where this can be a synonym ofВ saccharide. The carbohydrates (saccharides) will be divided into four chemical teams: В monosaccharides, В disaccharides, В oligosaccharides, andВ polysaccharides. In general, the monosaccharides and disaccharides, that are smaller (lowerВ molecular weight) carbs, are commonly reported assugars.[6]В The wordВ saccharideВ comes from theВ GreekВ wordВ ПѓО¬ОєП‡О±ПЃОїОЅВ (sГЎkkharon), meaning " sugar. " While the technological nomenclature of carbohydrates can be complex, the names of the monosaccharides and disaccharides very often result in the suffixВ -ose. For example , В grape sugarВ is the monosaccharideВ glucose, В cane sugarВ is the disaccharideВ sucrose, and milk glucose is the disaccharideВ lactoseВ (see illustration). Carbs perform several roles in living microorganisms. Polysaccharides provide for the storage ofВ energyВ (e. g., В starchВ andВ glycogen), and as strength components (e. g., В cellulosein plants andВ chitinВ in arthropods). The 5-carbon monosaccharideВ riboseВ is an important element ofВ coenzymesВ (e. g., В ATP, В FAD, andВ NAD) plus the backbone with the genetic molecule known asВ RNA. The related deoxyribose can be described as component of GENETICS. Saccharides and the derivatives consist of many other importantВ biomoleculesВ that play key roles in theimmune system, В fertilization, preventingВ pathogenesis, В blood clotting, andВ development.[7]InВ food scienceВ and in many simple contexts, the word carbohydrate often means anyВ foodВ that is specially rich in the complex carbohydrateВ starchВ (such asВ cereals, В bread, andpasta) or simple carbs, such asВ sugarВ (found inВ candy, В jams, andВ desserts).
