Homovanillic acid C화학적 특성, 용도, 생산
개요
Homovanillic acid (HVA) is a dopamine metabolite. It is formed via deamination of dopamine by monoamine oxidase (MAO) to produce 3,4-dihydroxyphenylacetic acid (DOPAC; ) followed by DOPAC metabolism by catechol-O-methyltransferase (COMT). HVA undergoes hydrogen peroxide-dependent oxidation in the presence of horseradish peroxidase to form a fluorescent dimer that displays excitation/emission maxima of 312/420 nm, respectively. It has been used to quantify hydrogen peroxide production in macrophages and neutrophils.화학적 성질
