By: Adrienne Gebele. What is PKU?. 1. Inherited disorder. Occurrence varied due to ethnicity and geography. About 1 and 10,000 to 15,000 infants are born with in the U.S.. People born with PKU have an inactive liver enzyme which causes a dangerous build up of phenylalanine in the blood.
By Kevin Zhu, Walter Chen, and. 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. .

What is PKU?. PKU is an inherited disorder that is an error of metabolism that increases the levels of a substance in the blood called phenylalanine hydroxylase.. Phenylalanine is an important amino acid and the body needs it for health; you get it from food. It is a building block for proteins in the body..
THE EXCRETION OF AMMONIUM IONS. A part of NH4+ that is formed in the degradation of amino acids is used for the biosynthesis of nitrogen compounds. In most of the land living vertebrates the excess NH4+ is converted in urea and in that form is excreted. In birds and reptiles it is converted into uric acid and in aquatic animals it is directly excreted as urea..
Plants and bacteria produce all of their amino acids using NH. 4. +. and NO. 3. –. .. Humans can synthesize 9 of the 20 amino acids found in their proteins.. Nonessential amino acids are synthesized in the body, while essential amino acids must be obtained from diet..
