Levodopa is an amino acid precursor of dopamine with antiparkinsonian properties. Levodopa is a prodrug that is converted to dopamine by DOPA decarboxylase and can cross the blood-brain barrier. When in the brain, levodopa is decarboxylated to dopamine and stimulates the dopaminergic receptors, thereby compensating for the depleted supply of endogenous dopamine seen in Parkinson's disease. To assure that adequate concentrations of levodopa reach the central nervous system, it is administered with carbidopa, a decarboxylase inhibitor that does not cross the blood-brain barrier, thereby diminishing the decarboxylation and inactivation of levodopa in peripheral tissues and increasing the delivery of dopamine to the CNS.

Function and Application of Levodopa CAS 59-92-7
Levodopa, also known as L-DOPA (CAS 59-92-7), is a medication used to treat the symptoms of Parkinson's disease. It is an amino acid that is converted into dopamine in the brain. Dopamine is a neurotransmitter that helps to regulate movement, mood, and other functions in the brain.

The primary function of levodopa is to increase dopamine levels in the brain. This helps to alleviate the symptoms of Parkinson's disease, which is caused by a deficiency of dopamine in the brain. Parkinson's disease symptoms include tremors, stiffness, and difficulty with movement and coordination.

Levodopa is typically administered in combination with a peripheral decarboxylase inhibitor (PDI) such as carbidopa or benserazide. These PDIs prevent levodopa from being broken down in the bloodstream, which allows more of it to reach the brain. This combination is known as carbidopa/levodopa or benserazide/levodopa.

Levodopa is one of the most effective medications for treating Parkinson's disease, and it can improve quality of life for many patients. However, it is not a cure for the disease and may have side effects such as nausea, dizziness, and dyskinesias (involuntary movements).
