Dopa and Dopamine

L-Dihydroxyphenylalanine (L-Dopa or Levodopa) is an amino acid that functions biologically as a metabolic precursor to the neurotransmitter dopamine (DA).  L-Dopa is decarboxylated to dopamine by the enzyme DOPA decarboxylase.  Due to its structural similarity to dopamine and its blood-brain accessibility, L-dopa is a commonly administered treatment for Parkinson’s disease (PD).  CIL is pleased to offer a variety of stable isotope-labeled standards of L-dopa and dopamine for research use applications.  These standards are available in their neat and/or solution form, with their unlabeled analogues additional available for qualitative/quantitative research purposes.
