The effects of sodium arsenate on the free amino acid levels in erythrocytes and plasma in rats.
The effects of arsenate on the levels of free amino acids in rat plasma and red blood cells have been investigated. The biggest changes occur in the branched-chain amino acids valine, isoleucine and leucine which are markedly decreased. The levels of several other amino-acids also change. The effects on the amino acids are not due to a change in the food intake caused by dosing with arsenate. This has been shown by comparing the results with those on fasting rats (40 h). Branched-chain amino acids in particular are markedly increased in plasma of fasting rats as opposed to a decrease in arsenate-treated rats.
