What is Tyrosin?
Tyrosin, also known as 4-hydroxyphenylalanine or L-Tyrosine, is a non-essential amino acid that the body synthesizes from another amino acid called phenylalanine. It is named from the Greek tyros , which is projected into the "cheese" because it is found in casein protein in cheese and other dairy products. Other natural food sources include fish, avacados, bananas, lima beans, almonds, peanuts and sunflower and pumpkin seeds.
This amino acid plays an important role in metabolism. For one thing, interact with proteins that are subject to signal transduction to start different cellular processes. Tyrosine receptor kinases serve as paths to transport phosphate compounds in a process known as phosphorylation that provides phosphotyrosin. These activities include virtually every protein in the body and are responsible for the regulation of the production of several enzymes. In addition, Tyrosin is the forerunner of several other substances, including neurotrans armoting chemikyals, hormones produced by thyroid,pituitary and adrenal glands and melanin skin pigment. These neurotransmitters are connected to signaling between nerve cells and synapses in the brain. These agents also affect mood and libido, and therefore these substances are sometimes called "feeling good hormones". In fact, several studies show that complementing this amino acid can help alleviate chronic stress, anxiety and mild depression.
The real lack of tyrosine is rare, but some syndromes are abnormal. For example, oculocutaneous albinism is characterized by the inability to synthesize melanin from the amino acid. Phenylketonuria is marked by the inability to synthesize phenylalanine into tyrosine, a condition that can cause brain damage. Although this condition may be a shortage, diet phenylalanine must be strictly avoiding and must be under the supervision of Tyrosine supplementation. Low levels can also compare to low HLADinami thyroid hormone, a condition that can promote hypothyroidism and worsen the functioning of the central nervous system.
Because there are few cases where tyrosine supplementation is needed, there are no standard dietary recommendations. However, in the absence of unusual syndromes, such as the above, low levels may be indicated by low body temperature or low blood pressure. Consultation with a qualified medical physician is recommended before supplementing this amino acid.
If tyrosine supplementation is found to be necessary in the form of a tablet or capsule in units between 50-1,000 mg. To facilitate absorption, it is recommended that supplements are used by food that includes carbohydrates, preferably just leaving to bed. In addition, the use of vitamin B6, folic acid - or vitamin B9 as folate - and copper also helps to increase the absorption of this amino acid.
