Sachin Patro. Definition. 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. . Summer Institute – Sept. 11, 2011. Teachable Unit.
