Phenylalanine reaction
WebPhenylalanine hydroxylase (PheH), a liver enzyme that catalyzes the hydroxylation of excess phenylalanine in the diet to tyrosine, is activated by phenylalanine. WebThe diminished phosphate clearance associated with renal failure leads to elevated levels of blood phosphate and consequently increases in circulating FGF23; this, in turn, further lowers levels of 1,25 (OH)2 D 3 and calcium.
