D-(+)-Glucono-1,5-lactone CAS 90-80-2
D-(+)-Glucono-1,5-lactone CAS 90-80-2 ndi mankhwala ogwiritsidwa ntchito m'njira zambiri omwe amagwiritsidwa ntchito kwambiri mu chakudya, mankhwala ndi zina. Glucono Delta Lactone imapezeka mu chilichonse kuyambira tofu yofewa yomwe timadya tsiku lililonse mpaka zinthu zina zopha mankhwala. Ndi "mankhwala ofatsa komanso ogwira ntchito m'njira zambiri" ofunikira kwambiri popanga mafakitale.
Gluconolactone ndi ester yomwe imasowa madzi pakati pa gulu la carboxyl la gluconic acid ndi gulu la hydroxyl la intramolecular, ndipo ester yomwe imasowa madzi pakati pa gulu la hydroxyl pa atomu yachisanu ya carbon (δ), yotchedwa gluconol-delt-lactone; Ester yomwe imasowa madzi ndi gulu la hydroxyl pa atomu yachinayi ya carbon (gamma-position) imatchedwa glucono-gamma-lactone. Kristalo. Ili ndi kukoma kosiyana ndi gluconic acid.
