"WebOur study found that the phenylalanine metabolic pathway was significantly changed in the serum metabolome of ESRD rats. For instance, the contents of L-phenylalanine and L-tyrosine were decreased, while the content of hippurate was increased. After PD and UCG treatment, phenylalanine metabolism gradually approached the normal level. " - Phenylalanine and tyrosine metabolism
