Glutathione is a powerful antioxidant that helps brighten skin by inhibiting the enzyme tyrosinase, which is responsible for melanin production
For the solubility test, cell pellet from 250 ml (2 10 12 cells) culture was harvested and 1250 L of a lysis and solubilization buffer containing 50 mM TrisCl pH 7.4, 1 mM EDTA, 10 mM -mercaptoethanol, 1% Triton-X 100, 300 mM NaCl, 1 mM PMSF and 500 L BugBuster Protein Extraction Reagent was added, maintaining the ratio of cells to buffer as ~1.6 10 12 cells/ml of buffer
Notably, the drugs may influence bone metabolism through indirect pathways like weight loss, anti-inflammatory effects, or direct receptor activity on bone cells, the authors speculate
