Liposomal glutathione costs more to manufacture, because the lipid-encapsulation process is specifically built to help more of the active molecule survive digestion intact
the folate-containing peptidyl fragment Pte-Glu-(AA) n -NH(CHR 2 )C0 2 H (3) is prepared by a polymer-supported sequential approach using standard methods, such as the Fmoc-strategy on an acid- sensitive Fmoc-AA-Wang resin (1), as shown in the following Scheme: Scheme R is Fmoc R 2 is the desired appropriately-protected amino acid side chain DIPEA is TBAF tetrabutylammonium fluoride Appropriately protected amino acid building blocks such as Fmoc-Glu-OiBu, Fmoc-D-Glu-OiBu dressing N 10 -TFA-Pte-OH, and the like, are used, as described in the Scheme, and represented in step (b) by Fmoc-AA-OH
A common approach is 2-3 mL BAC water per 10 mg vial
They typically arrive pre-mixed in specific concentrations, commonly 2.5 mg/mL or 5 mg/mL
However, this is controversial, and more evidence is needed
