Urine p-hydroxyphenylpyruvate

The tyrosine in humans comes from the hydroxylation of phenylalanine in food and in vivo, and then catabolism through different pathways. A small portion of tyrosine is metabolized into dopa. Further become dopamine, norepinephrine and adrenaline; most of the decomposition of tyrosine is converted into uric acid, further decomposed into acetoacetate and fumaric acid, rare hereditary p-hydroxyphenylpyruvate oxidase or urinary acid oxidation Tyrosinemia and black urine occur in the absence of enzymes. Increased urinary p-hydroxyphenylpyruvate in tyrosinemia may have severe liver damage, and children often die in infancy.
