摘要：Metabolic pathways of cyanate in rats were studied by means of measurements of cyanate, carbamyl phosphate and S-carbamyl group. Approximately 30-50% of cyanate administered to rats (0.5 mmol/kg body weight) was found in buffered gastric contents, and was also detected as ammonia liberated by acid hydrolysis. However, the gastric excretion of cyanate was a temporary phenomenon just after cyanate administration. Biliary and urinary excretion of cyanate and acid-soluble S-carbamyl group are minor metabolic pathways.
