WebCrystals were generated by preparing a saturated trehalose solution (46.6%w/w, the solubility of trehalose dihydrate at 20 °C).2846.6 g of trehalose dihydrate (calculated as anhydrous) was dissolved in 100 g of distilled (filtered 0.45 μm) distilled water. The solution was left to recrystallize by slow evaporation at room temperature. Trehalose is a nonreducing sugar formed from two glucose units joined by a 1–1 alpha bond, giving it the name α-D-glucopyranosyl-(1→1)-α-D-glucopyranoside. The bonding makes trehalose very resistant to acid hydrolysis, and therefore is stable in solution at high temperatures, even under acidic conditions. The bonding keeps nonreducing sugars in closed-ring form, such that the aldehyde or ketone end groups do not bind to the lysine or arginine residues of proteins (a process …
WebApr 1, 2010 · Powdered trehalose dihydrate was obtained through Pfanstiehl. Primary drying of both crystalline and amorphous trehalose was conducted in this study using an Edwards Super Modulyo lyophilizer unit with a Welch DuoSeal vacuum pump (model 1376) capable of producing pressure of 100 mbar. WebThe commercially available trehalose dihydrate takes in general a crystalline state, but tre-halose dihydrate microspheres prepared by using spray-drying method are in an amorphous state. We have prepared amorphous anhydrous trehalose by using melt-quenched method from crystalline trehalose dihydrate.
