D-(+)-Glucono-1,5-lactone CAS 90-80-2
D-(+)-Glucono-1,5-lactone CAS 90-80-2 yog ib qho tshuaj sib xyaw ua ke uas siv dav hauv zaub mov, tshuaj thiab lwm yam teb. Glucono Delta Lactone tuaj yeem pom muaj nyob rau hauv txhua yam los ntawm cov taum pauv mos uas peb noj txhua hnub mus rau cov tshuaj ntxiv. Nws yog ib qho tseem ceeb "tus neeg sawv cev ua haujlwm ntau yam" hauv kev tsim khoom lag luam.
Gluconolactone yog ib qho ester uas qhuav ntawm pawg carboxyl ntawm gluconic acid thiab pawg hydroxyl intramolecular, thiab ib qho ester uas qhuav ntawm pawg hydroxyl ntawm qhov thib tsib (δ) carbon atom, hu ua gluconol-delt-lactone; Cov ester qhuav nrog pawg hydroxyl ntawm qhov thib plaub (gamma-position) carbon atom hu ua glucono-gamma-lactone. Ib qho siv lead ua. Nws muaj qhov qab zib sib txawv dua li gluconic acid.
