IGlucono-Delta-Lactone(GDL)｜90-80-2
IiNkcazo zeeMveliso
IGlucono delta-lactone (GDL) sisidibaniso sokutya sendalo esinenombolo E575esetyenziswa njengesequestrant, iasidi, okanye ukunyanga, ukukha, okanye igwele. I-lactone (i-cyclic ester) ye-D-gluconic acid. I-GDL ecocekileyo ngumgubo omhlophe wekristale ongenavumba.
I-GDL idla ngokufumaneka kubusi, kwincindi yeziqhamo, kwizithambisi zobuqu, nakwiwayini[catshulwa]. I-GDL ayithathi hlangothi kodwa i-hydrolyzes emanzini ukuya kwi-gluconic acid ene-acidic, yongeza incasa emnandi ekutyeni, nangona iphantse ibe sisithathu sobumuncu be-citric acid. I-metabolized kwi-glucose; igram enye ye-GDL ivelisa phantse umlinganiselo ofanayo wamandla e-metabolic njengegram enye yeswekile.
Ngaphezulu kwamanzi, i-GDL ifakwe i-hydrolyzed kwi-gluconic acid, kunye nebhalansi phakathi kwefom ye-lactone kunye nefom ye-asidi esekwe njenge-chemical equilibrium. Izinga le-hydrolysis ye-GDL yonyuka ngobushushu kunye ne-pH ephezulu
