Dopamine β-hydroxylase (Dopamine beta-hydroxylase, Dopamine beta-monooxygenase) is an enzyme that in humans is encoded by the DBH gene. Dopamine β-monooxygenase catalyzes the chemical reaction with 3 substrates of 3,4-dihydroxyphenethylamine, ascorbate, and O2, whereas its 3 products are noradrenaline, dehydroascorbate, and H2O. Dopamine β-hydroxylase belongs to the family of oxidoreductases, specifically those acting on paired donors, with O2 as oxidant and incorporation or reduction of oxygen. Dopamine β-hydroxylase participates in tyrosine metabolism. Dopamine β-hydroxylase has 3 cofactors: copper, PQQ, and Fumarate. Dopamine β-hydroxylase is in the catecholamine biosynthetic pathway. Dopamine β-hydroxylase has been shown to be associated with decision making and addictive behaviors such as alcohol and smoking, attention deficit hyperactivity disorder, and also with neurological diseases such as Schizophrenia and Alzheimer's.

    Cuprizone
    		≥99.0%
    Cuprizone is a copper chelating agent that forms a deep blue copper ketone complex with copper (II). The copper ketone reaction can be used in colorimetric tests for the presence of trace copper. Cuprizone can be used to induce some schizophrenia-like behavior in mice. Cuprizone acts on copper enzymes, including SOD1, cytochrome oxidase, and DβH, thereby causing oxidative stress and increasing DA levels in certain brain regions such as the medial prefrontal cortex (PFC).
