The safety of l-alanyl-l-glutamine (l-AG) derived by fermentation using a recombinant Escherichia coli strain containing the l-amino acid alpha-ligase gene from Bacillus subtilis, was assessed in acute and subchronic toxicity studies in the rat. l-AG was tested in vitro in a bacterial reverse mutation assay and in a chromosome aberration assay. l-AG was not acutely toxic when administered to Sprague-Dawley rats by gavage at 2000mg/kg bw. In a 14-day range-finding study, l-AG at up to 5% in the… CONTINUE READING
