What does phenylalanine hydroxylase do in the body?
What does phenylalanine hydroxylase do in the body?
Phenylalanine hydroxylase is responsible for the conversion of phenylalanine to another amino acid, tyrosine. The enzyme works with a molecule called tetrahydrobiopterin (BH4) to carry out this chemical reaction.
How is phenylalanine hydroxylase treated?
The mainstay of treatment for hyperphenylalaninemia involves a low-protein diet and use of a phenylalanine-free medical formula. This treatment must commence as soon as possible after birth and should continue for life. Regular monitoring of plasma phenylalanine and tyrosine concentrations is necessary.
What disease is due to defective phenylalanine hydroxylase?
Phenylketonuria (fen-ul-key-toe-NU-ree-uh), also called PKU, is a rare inherited disorder that causes an amino acid called phenylalanine to build up in the body. PKU is caused by a defect in the gene that helps create the enzyme needed to break down phenylalanine.
What is phenylalanine hydroxylase USED FOR?
The tyrosine synthesized by the action of phenylalanine hydroxylase is required for the synthesis of various neurotransmitters that act on the nervous system and also control key functions like respiration and heart rate.
What is phenylalanine converted to?
Phenylalanine is converted into tyrosine, which then becomes converted into catecholamine neurotransmitters.
What foods have high phenylalanine?
Phenylalanine is found in most protein-containing foods such as milk, eggs, cheese, nuts, soybeans, chicken, beef, pork, beans and fish.
Is PKU considered a disability?
The Social Security Administration does recognize phenylketonuria in its Blue Book of Medical Listings under Section 10.00 in paragraph C. 2. However, a diagnosis of the condition itself is not enough to qualify an individual for Social Security Disability benefits, regardless of the SSA’s listing inclusion.
Why phenylalanine is bad for you?
Phenylalanine can cause intellectual disabilities, brain damage, seizures and other problems in people with PKU . Phenylalanine occurs naturally in many protein-rich foods, such as milk, eggs and meat. Phenylalanine is also sold as a dietary supplement.
