Phenylalanine concentration
WebIndividuals with phenylketonuria (PKU) must follow a lifelong, low-phenylalanine (phe) diet to prevent brain damage. The diet requires ingestion of an amino acid formula and compliance is poor after early childhood. Glycomacropeptide (GMP) from cheese whey is uniquely suited to the PKU diet because it is a palatable dietary protein that is naturally free of phe. WebMar 16, 1999 · When the HPA is severe (blood phenylalanine > 1.2 mM, 20 times above normal levels of 0.055–0.060 mM), it leads to the disease known as classical phenylketonuria (PKU), which, if not treated by a low-phenylalanine diet from early infancy, leads to postnatal brain damage and mental retardation (3).
