Tyramine is a compound similar to the amino acid tyrosine.

Both receptor and non-receptor tyrosine kinases play pivotal roles in these signaling pathways.

Tyrosine is converted into DOPA by the enzyme tyrosine is converted into DOPA by the enzyme tyrosine hydroxylase.

Both receptor and non-receptor tyrosine kinases play pivotal roles in these signaling pathways.

Phenylketonuria-A condition caused by a genetic error of the body's metabolism, characterized by the absence of phenylalanine hydroxylase (an enzyme that converts phenylalanine into tyrosine).

The hairbulb pigmentation test is used to identify carriers by incubating a piece of the person's hair in a solution of tyrosine, a substance in food which the body uses to make melanin.

It measures the rate at which hair converts the amino acid tyrosine into another chemical (3,4-dihydroxyphenylalanine, or DOPA), which is then made into pigment.

The hair converts tyrosine with the help of an enzyme called tyrosinase.

In some types of albinism, a genetic defect in tyrosinase means that the amino acid tyrosine cannot be converted by tyrosinase into melanin.

Tyrosinase-An enzyme in a pigment cell which helps change tyrosine to dopa during the process of making melanin.

This enzyme converts (metabolizes) the amino acid called phenylalanine into another amino acid, tyrosine.

The brain makes dopamine from the amino acid tyrosine.

PKU patients who do not consume enough tyrosine in their diets cannot produce sufficient amounts of dopamine.

Some research suggests that nerve cells of PKU patients also have difficulty absorbing tyrosine.

This abnormality may explain why many PKU patients who receive sufficient dietary tyrosine still experience some form of learning disability.

Melanin is made from the amino acid tyrosine, which is lacking in untreated cases of PKU.

Physiologically, PKU patients show high levels of phenylalanine and low levels of tyrosine in the blood.

Another, more accurate test procedure for PKU measures the ratio (comparison) of the amount of phenylalanine to the amount of tyrosine in the blood.

Typical diets prescribed for PKU patients provide very small amounts of phenylalanine and higher quantities of other amino acids, including tyrosine.

A specialized PKU diet can cause abnormal fluctuations in tyrosine levels throughout the day.

Thus, some health professionals recommend adding time-released tyrosine that can provide a more constant supply of this amino acid to the body.

It should be noted that some PKU patients show signs of learning disabilities even with a special diet containing extra tyrosine.

Research studies suggests that these PKU patients may not be able to process tyrosine normally.

The maturation process depends on an enzyme called Bruton's agammaglobulinemia tyrosine kinase (Btk).

Bruton's agammaglobulinemia tyrosine kinase (Btk)-An enzyme vital for the maturation of B cells.

The trouble is that phenylalanine is a requirement for the body to synthesize tyrosine.

Once in your body, this amino acid is converted into tyrosine.

Tyrosine is essential for making proteins as well as thyroid hormone and brain chemicals.

Many contain increased amounts of tyrosine, which speeds up the production of melanin in the body.

Each of the products are infused with the patented Cellex-C complex, a powerful combination of L-ascorbic acid, tyrosine and zinc.
