What does PKU stand for?
Phenylketonuria (PKU) is not an eating disorder. It is an inherited disorder which the body cannot break down phenylalanine, which is a part of protein. If PKU is not treated soon after birth, it can cause brain and nervous system damage.
Effects of this recessive disorder can be completely overcome by regulating the diet of the affected individual?
Phenylketonuria, if is detected in the newborn, a special diet low in phenylalanine can usually promote development and prevent retardation.
What is a coliac?
A colic is an abdominal disorder that affects the small intestines mostly in infants. This is said to be an autoimmune disorder and entails sharp pains in the digestive tract among other symptoms.
Is alkaptonuria caused by a recessive or dominant allele?
Phenylketonuria is an autosomal recessive genetic disorder. The enzyme phenylalanine hydroxylase is necessary to metabolize phenylalanie, but when this enzyme doesnt work, phenylaline accumulates and is detected in the urine. The disease is detected during pregnancy, and if treated right away the newborn can develop normally. However, if left untreated, the brain will not develop properly.
The lack of which enzyme causes galactosemia?
Galactosemia is a genetic disorder which is caused by a lack of the GALT enzyme. This is essential in breaking down the milk sugar galactose.
Is what is phenylketonurics?
Phenylketonuria (PKU) is an autosomal recessive genetic disorder characterized by a deficiency in the enzyme phenylalanine hydroxylase (PAH). This enzyme is necessary to metabolize the amino acid phenylalanine to the amino acid tyrosine. When PAH is deficient, phenylalanine accumulates and is converted into phenylpyruvate (also known as phenylketone), which is detected in the urine.
What is phenylketonuric?
Phenylketonuria (PKU) is an autosomal recessive genetic disorder characterized by a deficiency in the enzyme phenylalanine hydroxylase (PAH). This enzyme is necessary to metabolize the amino acid phenylalanine to the amino acid tyrosine.

What problem would people have if they did not have phenylalanine hydroxylase?
Phenylalanine hydroxylase deficiency, traditionally known as phenylketonuria or PKU. Untreated it can cause:Intellectual disability, behavioral, emotional and social problems, psychiatric disorders. neurological problems that may include seizures.Fair skin and blue eyes, because phenylalanine cannot transform into melanin — the pigment responsible for hair and skin tone and an abnormally small head (microcephaly).There are different levels of this disorder and a diet very low in proteins can help. This is the first genetic disease that is tested for in infants.
In phenylketonuria what amino acid becomes conditionally essential?
Tyrosine, PKU is a inherited disorder that is characterized by failure to metabolize the amino acid phenylalanine to tyrosine.
What is the treatment for phenylketonuria?
The best treatment of phenylketonuria is a diet that is extremely low in phenylalanine during childhood. A person can also take fish oil supplements and iron supplements to help treat some of the symptoms.
What is penylketonuria?
Penylketonuria is a serious condition in which a baby is born without the ability to properly breakdown the essential amino acid phenylalanine. It is a genetic disorder
Is an inherited autosomal recessive disorder in which a person lacks the enzyme that is necessary to break down the amino acid phenylalanine phenylalanine then breaks down to form chemicals that?
PKU!
In an individual has no genetic code for phenylalanine?
An individual who cannot produce phenylalanine would not be viable so I believe what you are asking about is Phenylketonuria which is a genetic disorder found is infants who cannot properly digest phenylalanine (they can manufacture it).Hospitals test for this disorder in newborns because it is imperative to place babies that test positive on a strict diet to prevent the mental retardation that is associated with the disorder. Early intervention results in a nearly normal life.
If an individual has no genetics code for phenylalanine what kind of danger does it pose to him?

What is heterogenous autosomal recessive disease?
autosomal recessive disease - a disease caused by the presence of two recessive mutant genes on an autosome some of ex. areCystic Fibrosis: Cystic fibrosis is a hereditary disease affecting the exocrine (mucus) glands of the lungs, liver, pancreas and intestines, causing progressive disability due to multisystem failure.Phenylketonuria: A metabolic disorder where there is a deficiency of the enzyme phenylalanine hydroxylase which leads to a harmful buildup of the phenylalanine in the body. Normally the phenylalanine is converted into tyrosine.Sickle Cell Anemia: Sickle cell anemia is an inherited blood disorder characterized by red blood cells which are crescent-shaped rather than the normal doughnut shape. These abnormally shaped red blood cells are unable to function normally and tend to undergo premature destruction which leads to anemia.
What causes this malfunction in the digestive system?
A disorder in excretion of water by the large intestine.B disorder in absorption of water by the large intestine.C disorder in release of digestive enzymes by the large intestine. The answer is A.
Is there anything bad in phenylalanine?
No, it is simply put on packages and soda cans because there is a specific disease that can harm people if they ingest it. The disease is phenylketonuria, or PKU. It is a genetic disorder that keeps your body from metabolizing phenylalanine, which is an amino acid. If you have PKU and eat too much phenylalanine, it will cause mental retardation. NutraSweet has phenylalanine in it, so they don't want PKU sufferers to use it for obvious reasons. So...phenylalanine is okay for you if you don't have PKU.
