Nevertheless, cystine is taken up by some cells (i.e., endothelial cells) and, given the high reducing conditions, is intracellularly reduced to cysteine, employed for the synthesis of GSH ( The last GSH synthetic process is the one depending on the conversion of the oxidized dimer GSSG to 2 reduced GSH molecules in cells by glutathione reductase (GR), an ubiquitous enzyme of the family of disulfide reductases, in the presence of NADPH and flavin adenine dinucleotide -FAD-

Different reconstitution volumes produce different concentrations from the same vial: 50mg vial + 2ml water = 25mg/ml (very concentrated) 50mg vial + 2.5ml water = 20mg/ml (concentrated) 50mg vial + 5ml water = 10mg/ml (standard) 50mg vial + 10ml water = 5mg/ml (dilute) Higher concentrations require smaller injection volumes but may exceed solubility limits for some peptides
