Glucose: A sunadarai Properties na da misali

A mafi sauki na sugars, duniya kudin na makamashi da cewa kwakwalwa fi son da kuma mutunta zuciya tsoka. Idan wani mutum ya keta ikon sunadaran, da kuma matakin na glucose a cikin jini da dama a kasa a wasu na kullum, akwai zo da wani makawa asarar sani da kuma mutuwa. Ciwon sukari mellitus matsayin Pathology assimilation wannan abu take kaiwa zuwa "yunwa amidst yalwa." Saboda haka, da abinci, dauke da glucose, ya kamata a bi tare da taka tsantsan, ba kawai ga masu ciwon sukari - da tsarin na sukari metabolism tsari ne hadaddun.

Ta hankali karatu a cikin kwayoyin sunadarai darussa, bioorganic sunadarai da Biochemistry. Mene ne glucose? Its sinadaran Properties kara daga tsarin fasali na ginin. Su biyu Musulunci - shi lokaci guda yana da wani aldehyde kungiyar da kuma hydroxyl kungiyar, Ina nufin, a gaskiya, shi ne duka wani aldehyde da wani polyhydric barasa (a matsayin rukuni na biyu na farko da na biyu da irin a cikin tsarin ba shi kadai).

Dole ne mu fara da aldehyde Properties. A bambanci, fructose, glucose da kuma sinadaran Properties nuna ta aldose irin - wato, yana yiwuwa su yi dauki na azurfa madubi a amince. Wannan dada kyau dauki, bukata tsarki reagents da kuma kayan aiki. Saboda haka, daga wani ammoniacal azurfa bayani, ɗaɗɗaure a cikin hadaddun, da karfe da aka samu. Idan duk abin da ya tsabta, shi dai itace kyawawan santsi fim, kamar madubi, wanda ya sa bayyanar da take. Amma idan wani abu ya ba su da tsabta, ba za ka samu sako-sako da clumps na launin toka taro, da mummuna da kuma iya shiga cikin saba experimenter yaudarar. Saboda haka wanke vials yadda ya kamata!

Abin da kuma "sanin" yadda glucose? Chemical kaddarorin da aldehyde irin suna ba kawai a tsare ta maida martani azurfa madubi. Wani sosai hankula dauki ne hydrogenation, Ina nufin abin da aka makala na hydrogen zuwa aldehyde kungiyar a gaban nickel karfe mai kara kuzari. Wannan suranta barasa sorbitol. Af, shi ne wani m aiwatar nunarsa, cheap da sauki, duk da haka, fara abu ne mai hadaddun masara sitaci maimakon tsarki glucose amma sitaci ne hydrolyzed da ita.

A kalla biyu kaddarorin da aldehyde ne glucose. Chemical Properties, da gaskatashi, giya yanayin wannan abu, kuma ya wanzu. Alal misali, ingantaccen dauki ga wani hydroxyl kungiyar. Kawai ƙara a wani alkaline matsakaici da gwajin samfurin jan hydroxide. Saboda haka, idan glucose ne ba, a jan precipitate da aka kafa, da kuma samu cikakken bayani kasance mai haske blue. Wannan dauki ne hujja giya Properties na glucose.

Amma akwai wani ban sha'awa dauki cewa yana jawo da yisti da kuma fuskantar kusan kome da kome. Abin da ke sa glucose? A sunadarai Properties suna a hankali alaka ilmin halitta. By da enzymes kafa ethanol, ya hallaka fungi biyu mahadi a kowane kwayoyin, haddasa samuwar carbon dioxide. Irin wannan ne da sinadaran Properties na glucose. Wannan samar da wani halayyar wari: kawai sansana da yisti kullu - da kuma tabbatar da cewa yana da gaske isasshen ethanol.

ko glucose ne hadaddun? Jiki da kuma sinadaran Properties shi ne quite iya faɗi bisa laákari da dabara, amma abu da yake riƙe da yawa asirai: misali, wasu siffofin na jiki undigested.
