D-Dopa

Description:

D-Dopa, or Dihydroxyphenylalanine, is an amino acid that serves as a precursor to neurotransmitters, particularly dopamine. It is a chiral compound, existing in two enantiomeric forms: L-Dopa and D-Dopa, with L-Dopa being the biologically active form commonly used in the treatment of Parkinson's disease. D-Dopa is less prevalent in biological systems and is primarily of interest in research contexts. The compound has a molecular formula that includes a phenolic hydroxyl group, contributing to its reactivity and potential interactions in biochemical pathways. D-Dopa is typically characterized by its white crystalline appearance and is soluble in water, which facilitates its use in various experimental applications. Its CAS number, 5796-17-8, uniquely identifies it in chemical databases, aiding in the retrieval of information regarding its properties, synthesis, and potential uses. While D-Dopa itself is not widely used therapeutically, studying its properties can provide insights into the mechanisms of neurotransmitter synthesis and the role of amino acids in neurological functions.

Controlled Product

CAS: 5796-17-8

D-DOPA is a precursor to dopamine that is commonly used in the treatment of Parkinson's disease. It is synthesized from L-tyrosine by the enzyme tyrosine hydroxylase. D-DOPA is also an intermediate in the biosynthesis of melanin and epinephrine. D-DOPA has been shown to be potent inducer of enzymes such as glutamate dehydrogenase and glutamate decarboxylase, which are involved in the synthesis of glutathione, glutamine, and GABA. Dopamine can also inhibit uptake by Streptococcus faecalis, an organism that causes bacterial vaginosis.
