DL-Dopa
Based on 1 Customer Validation
DL-Dopa is a dopamine precursor. It serves as a substrate for Mushroom Tyrosinase, which oxidizes it to dopaquinone, an intermediate in the DOPA-melanin polymerization process, and this reaction can be detected at 475 nm. DL-Dopa also forms synergistic hydrophobic and π-π stacking interactions with cationic surfactants. Its binding to cetylpyridinium chloride (HY-B1464) is stronger and exhibits better thermodynamic stability than its binding to benzalkonium chloride (HY-B2232). DL-Dopa can compensate for dopamine depletion in the brain and is applicable to research related to Parkinson's disease.

Human Endogenous Metabolite |
DL-Dopa (6.7 mM; 7 min) is oxidized by mushroom tyrosinase to form a colored product at 475 nm, and Kojic acid (HY-W050154) inhibits this oxidation rate in a concentration-dependent manner[1].
DL-Dopa (6.6-6.7 mM; 20 h) can be completely oxidized to Dopaquinone by mushroom tyrosinase; under in vitro conditions, in the presence of Kojic acid, Dopaquinone interacts with Kojic acid to form a yellow product at 335 nm instead of polymerizing into DOPA-melanin[1].
Oxidation of DL-Dopa (6.7 mM; 7 min) catalyzed by mushroom tyrosinase induces oxygen uptake, while Kojic acid inhibits the rate of this oxygen uptake in a concentration-dependent manner.[1]
