Yakasindimara yeBlue
Glucose ikemikari yakasanganiswa inoparadzirwa zvakanyanya munyika yezvipenyu. Zvinofungidzirwa kuti zvinomera zvinobudisa matani anosvika mabhiriyoni 100 gore negore kuburikidza nephotosynthesis!
Glucose mamorekuru zvakare chikamu cheakawanda makomisheni, senge sucrose, starch, cellulose. Glucose mune aqueous solution iri muchimiro chemhete (maisomeri maviri akasiyana mukumisikidzwa) ane diki musanganiswa weiyo fomu reketani. Mafomu ese ari maviri emhete anoshandurwa kuburikidza neketani fomu - chiitiko ichi chinodanwa mutation (kubva lat. Move = kuchinja).
Mumamiriro ekuenzanisa, zviri mukati memhando dzese dzeglucose molecule ndezvizvi zvinotevera (kujekesa, maatomu ekabhoni ane nhamba inoenderana nemaatomu ehaidrojeni anosiiwa pamibatanidzwa yemabhondi):
Iyo yakaderera yemukati yeketani fomu inokonzeresa maitiro eglucose (mushure mekushandisa, inodzoserwa kubva kune mhete mafomu), semuenzaniso, Trommer uye Tollens bvunzo. Asi aya handiwo ega kuita kwakasiyana-siyana kunosanganisira komboni iyi.
Mukuedza isu tichashandisa glucose, sodium hydroxide, NaOH uye methylene dhayi yebhuruu (mufananidzo 1), yakashandiswa, pakati pezvimwe zvinhu, segadziriro yeiyo aquarium. Wedzera imwe mhinduro yeNaOH (mufananidzo 2) yehuwandu hwakafanana uye madonhwe mashoma edhayi (mufananidzo 3) Zviri mukati meflask zvinoshanduka bhuruu (mufananidzo 4), asi inokurumidza kupera (mapikicha 5 ne6) Mushure mekudengenyeka, mhinduro inoshanduka bhuruu zvakare (mapikicha 7 ne8), uyezve kuchinja ruvara zvakare mushure mechinguva. Iyo nzira inogona kudzokororwa kakawanda.
Zvinoitika panguva yekuedza oxidation yeglucose kune gluconic acid (iyo aldehyde boka reketani fomu -CHO inoshanduka kuva carboxyl boka -COOH), kunyanya, munyu ye sodium yeiyi acid, iyo inoumbwa mune yakasimba alkaline reaction medium. Glucose oxidation inokonzerwa nemethylene blue, iyo oxidized fomu iyo yakasvibiswa kubva kune yakaderedzwa fomu (leukoprinciples, gr. leukemia = chena), yakasiyana nemuvara:
Ikozvino maitiro anogona kumiririrwa sezvizvi:
glucose + oxidized fomu yedhayi ® gluconic acid + yakaderedzwa fomu yedhayi
Kuita kuri pamusoro ndiko kunokonzera kutsakatika kweruvara rwebhuruu rwemushonga. Mushure mokuzunungusa zviri mukati meflask, okisijeni yakanyungudika mumvura mumhepo inokonzera iyo yakaderedzwa fomu yedhayi, semugumisiro wekuti ruvara rwebhuruu runowanikwa zvakare. Iyo nzira inodzokororwa kusvikira glucose yapera. Saka, methylene bhuruu inoita sechigadziriso chemhinduro.
