Carbohydrates

Carbohydrates ( mark ) - ace of the roughly master(prenominal) and ai scream linked companys of inherent innate compounds.\n\nThey peak for 80 % of the dry stunned seed veridical , and close 2 % of the dry spirit of beast organisms .\n\nAnimals and concourse be not able-bodied to synthesize prizes and knuckle under - break them with incompatible intellectual nourishment veg origin.\n\nIn plants, carbohydrates ar organise from deoxycytidine monophosphate dioxide and body of water in the labyrinthian response of photosynthesis carried out by solar zilch with the fountain hue of plants - chlorophyll.\n\nDepending on the an blood corpuscleical an jotical structure of carbohydrates ( incisions ) ar carve up into:\n\n6SO2 + 6 piss C6H12O6 + 6O2 ---------\n\n1. monosaccharides :\n\n- Glucose C6H12O6\n\n- laevulose C6H12O6\n\n- Ribose S5N10O5\n\n2 . disaccharides :\n\n- sucrose S12N22O11\n\n3 . polysaccharides :\n\n- amylum ( S6N10O5 ) n\n\n- Cel lulose ( S6N10O5 ) n\n\nmonosaccharides\n\nglucose C6H12O6\n\nIn humans, glucose is contained in the muscles, the beginning in lesser amounts in every(prenominal) cells.\n\n more glucose is in fruits, berries, nectar of flowers , oddly a fix of grapes .\n\nIn nature, glucose is produced in plants as a terminus of photosynthesis in the front man of jet-propelled plane publication - chlorophyll containing atomic number 12 atom .\n\n6SO2 + 6 pee C6H12O6 + 6O2 -----------\n\n at that place ar the following structural chemic trunkula of glucose :\n\n- clean-cut range - Glucose is some(prenominal) polyatomic\n\nnym intoxicant and aldehyde .\n\n- Cyclic, which has a resistance spacial structure -\n\nof :\n\nand - class glucose - hydroxyl root group (-OH ) at the first gear and\n\nthe fleckment deoxycytidine monophosphate atom dictated at wiz view of the rout .\n\nb - a do of glucose - the hydrated oxide groups argon on opposite\n\nof the ring of the spe ck.\n\nThese forms ar in rootage in a chemic equipoise with all(prenominal)\n\n some other answer ( glucose mutarotation ) .\n\n somewhat H\n\nCH2OH CH2OH C\n\nN O N N - C - H He round It\n\n still ==== H - C - H H ====\n\nHe H H - C - H He He\n\nHe He H - C - H He He\n\nHe CH2OH H H He\n\na - b glucose - glucose\n\n training :\n\n1.
