Levodopa,L-DOPA CAS NO.59-92-7

Description:

L-DOPA, also known as levodopa and l-3,4-dihydroxyphenylalanine, is an amino acid that is made and used as part of the normal biology of humans, as well as some animals and plants. Humans, as well as a portion of the other animals that utilize l-DOPA in their biology, make it via biosynthesis from the amino acid l-tyrosine. l-DOPA is the precursor to the neurotransmitters dopamine, norepinephrine (noradrenaline), and epinephrine (adrenaline), which are collectively known as catecholamines. Furthermore, l-DOPA itself mediates neurotrophic factor release by the brain and CNS.l-DOPA can be manufactured and in its pure form is sold as a psychoactive drug with the INN levodopa; trade names include Sinemet, Pharmacopa, Atamet, and Stalevo. As a drug, it is used in the clinical treatment of Parkinson's disease and dopamine-responsive dystonia.

l-DOPA has a counterpart with opposite chirality, d-DOPA. As is true for many molecules, the human body produces only one of these isomers (the l-DOPA form). The enantiomeric purity of l-DOPA may be analyzed by determination of the optical rotation or by chiral thin-layer chromatography (chiral TLC).

Function:

1 ) L-DOPA is anti-paralysis agitans. Through the blood-brain barrier into the brain tissue, but by the decarboxylation of dopa decarboxylase into dopamine, play a role.

2) L-DOPA can be used for essential tremor and paralysis paralysis agitans syndrome of non-drug immunogenicity, and in better light, severe, or the elderly poor.

3) L-DOPA can promote muscle growth,loss weight.

4) L-DOPA can increase bone density and reversal of osteoporosis.

5) L-DOPA can be dietary supplements.

6) L-DOPA can treat parkinsonism and Pakinsonism syndrome, hepatic coma,hub functions to improve the patient awake, symptom improvement.

7) L-DOPA can promote sleep,improve immune system.

8) L-DOPA can weight loss.

9)L-DOPA can increase bone density and reversal of osteoporosis,increase muscle strength,enhance libido and sexual performance
