Phenylketonuria (PKU) is a genetic disorder that is described by an lack of ability of the body to use the necessary amino acid called phenylalanine. Amino acids are the building blocks for body’s proteins. 'Essential' amino acids can only be attained from the food that we eat. Our body does not normally produce them. The 'classic PKU', the enzyme that breaks down phenylalanine hydroxylase, is absolutely or almost completely lacking. This enzyme normally turns phenylalanine to another amino acid called tyrosine. Without this ‘Classic PKU', phenylalanine and it’s other breakdown chemicals from other enzyme method, build up in the blood and body tissues. . e active ingredients because 1) they occur naturally and do not persist in the environment, 2) they are not toxic to mammals or other organisms tested, and 3) they are not likely to be toxic to plan UNIT IV:.

Because of the lack of neonatal symptoms, laboratory testing for elevated blood levels of phenylalanine is mandatory for detection. . Learning Objectives :. 1.

Phenylketonuria, an inborn error of metabolism inherited as an autosomal recessive trait (the PAH gene is located on chromosome 12q24), is caused by a deficiency or absence of the enzyme needed to metabolize the essential amino acid phenylalanine.
