The mechanistic basis for BPA hepatotoxicity involves multiple convergent pathways including oxidative stress-mediated lipid peroxidation damaging hepatocyte membranes, mitochondrial dysfunction compromising ATP synthesis, endoplasmic reticulum stress activating unfolded protein response pathways, and disrupted lipid metabolism promoting steatosis [61]
Second, some absorption of intact peptides does occur through the intestinal barrier
Look for: HPLC purity reported as a percentage (target 98% or above), molecular weight confirmation near 340.38 g/mol by mass spec, appearance (blue to blue-green powder or solution), water content by Karl Fischer titration, residual solvents within USP limits, and a third-party lab name with a report date
This suggests alternate mechanisms of radioprotection
