In the human body it is first converted to phenylbutyryl-CoA and then metabolized by mitochondrial beta-oxidation, mainly in the liver and kidneys, to the active form, phenylacetate. Phenylacetate conjugates with glutamine to phenylacetylglutamine, which is eliminated with the urine. It contains the same amount of nitrogen as urea, which makes it an alternative to urea for excreting nitrogen.A 5g tablet or powder of sodium phenylbutyrate taken by mouth can be detected in the blood within 15 minutes, and reaches peak concentration in the bloodstream within an hour. It is metabolized into phenylacetate within half an hour. See also
