Description
Dopamine is a neurotransmitter involved in synaptic plasticity, cognition, and the regulation of locomotor control. It is produced endogenously in the substantia nigra and ventral tegmental area but when administered exogenously cannot cross the blood brain barrier. L-DOPA is a metabolic precursor of dopamine that is capable of crossing the blood brain barrier. It is produced from L-tyrosine by trysosine hydroxylase and metabolized by catechol-O-methyl transferase (COMT). In the brain L-DOPA is converted to dopamine. It is conventionally used to increase dopamine concentrations in the brain as a treatment for Parkinson’s disease and stroke recovery. However L-DOPA has a short half-life and is known to elevate homocysteine concentrations in plasma, which can be neurotoxic and induce oxidative damage.More related product prices
