[Free amino acid concentration in the tissues of rats with different forms of thiamine deficiency].
The levels of free amino acids in rat tissues under thiamine deficiency induced by antivitamin (oxithiamine) and under thiamine-deficient diet were studied. Changes in the amino acid pool at these two forms of vitamin B1 deficiency were revealed. The most typical change consists in extensive accumulation of alanine and glutamate with a simultaneous decrease in the amount of many other essential and non-essential amino acids. The disturbances in the amino acid pool under thiamine deficiency may be probably regarded as resulting from inhibition of alpha-keto acid dehydrogenase activities.
