Phenylalanine metabolic pathway

WebGood evidence has confirmed that phenylketonuria (PKU) is not caused by a simple lack of phenylalanine hydroxylase. Dihydropteridine reductase deficiency as well as defects in biopterin metabolism may also cause the clinical features of phenylketonuria. Furthermore, these diseases do not respond to the standard treatment for phenylketonuria. WebPhenylketonuria (commonly known as PKU) is an inherited disorder that increases the levels of a substance called phenylalanine in the blood. Phenylalanine is a building block of proteins ( an amino acid) that is obtained through the diet. It is found in all proteins and in some artificial sweeteners.
