Possible Interaction: Cuprous and Vitamin C

“However, sucrose and detergents, biogenic amines, chlorpromazine, penicillins, vitamin C , paracetamol, hydrogen peroxides, or any compound that can reduce Cu2+ to Cu+ will produce the characteristic purple color associated with the binding of Cu+ with BCA and interfere with this method (4)(5).”

“The concept of using ascorbic acid as a mediator/ reducing agent in a Cu(I) catalyzed process is introduced and further demonstrated on a cross-coupling reaction of aryl iodides with disulfides.”

“In the presence of ascorbic acid in the peptide solution, the amount of Cu(i)-Aβ16 generated electrochemically was even higher.”
