Quizplus · Accepted Answer

Phenylketoneuria (PKU) is a genetic disorder that affects the catabolism (breakdown) of the amino acid phenylalanine. Individuals with PKU lack the enzyme phenylalanine hydroxylase, which is responsible for converting phenylalanine into tyrosine. As a result, phenylalanine and its byproducts, such as phenylpyruvic acid, accumulate in the body and can lead to intellectual disability and other neurological problems if left untreated.
