What is the connection between phenylalanine and Tyrosin?

both phenylalanine and tyrosine are aromatic amino acids that are used in proteins synthesis. In humans, phenylalanin is an essential amino acid that needs to be obtained from the diet. Tyrosin, on the other hand, can be synthesized from phenylalanine and is considered to be irrelevant amino acid. Both compounds can be changed to chemicals that affect mood and brain function. Because of these effects, phenylalanine and tyrosine are often considered nutritional supplements. There is a group of three amino acids that are collectively known as aromatic amino acids because they are connected to a phenyl circle. Phenylalanine and tyrosine have such a ring in their structure. Phenylalanine has only a phenyl circle, six carbon circles with three double bonds. Tyrosin is synthesized by enzyme phenylalanine hydroxylase that adds hydroxyl or oh to a circle of phenylalanine.

both phenylalanine and phenylalanine atyrosine is obtained from consuming foods with high protein content such as meat, dairy products,Avocado, soy products and certain nuts. Some people must be very careful and eat a low phenylalanine diet because they suffer from a genetic disorder called phenylketuria (PKU) in which phenylalanine is not metabolized. It can be built on a toxic level and cause retardation and death. In the United States, newborn children are tested for this genetic disease during the first few days of their lives.

Aspartam artificial sweetener is a common source of phenylalanine that people with PKU must avoid. This compound is a combination of aspartic and phenylalanine acid and is a common component in eating sodas. However, alternative sweeteners are beginning to be replaced.

amino acids can be found in two forms: D and L. These are mirror images and are known as stereoisomers. A common form of f or amino acid in the synthesis of proteins is a l-form. People get L-phenylalanin from their diet. D-phenylalanin is synthesized chemically. It is not involved in protein synthesis and is not metabolised to tyrosine. Phenylalanine supplements are sold in combinations of D-, L- and DL-phenylalanine (DLPA).

A number of exaggerated demands are made for health benefits in the use of phenylalanine as a nutrient supplement and should not be taken by everyone. It is clear from biochemical studies that phenylalanine and tyrosine begin blocks for neurotransmitter dopamine and hormones adrenaline and noradrenaline. Dopamine level changes can have great effects on mood disorders such as depression and diseases such as Parkinson. People with PKUs or who use antidepressants, as well as women who are pregnant or breastfeeding, should not use phenylalanine supplements.
