3,4-Dihydroxyphenylacetic acid (DOPAC) yog metabolite ntawm cov neurotransmitter dopamine.

Dopamine tuaj yeem hloov pauv mus rau ib ntawm peb yam tshuaj. Ib yam khoom ntawd yog DOPAC. Lwm qhov yog 3-methoxytyramine (3-MT). Ob qho ntawm cov tshuaj no tau ua tsis zoo los tsim homovanillic acid (HVA). Ob qho kev puas tsuaj cuam tshuam nrog cov enzymes monoamine oxidase (MAO) thiab catechol-O-methyl transferase (COMT), txawm hais tias yuav rov qab los: MAO catalyzes dopamine rau DOPAC, thiab COMT catalyzes DOPAC rau HVA; qhov COMT catalyzes dopamine rau 3-MT thiab MAO catalyzes 3-MT rau HVA. Qhov thib peb cov khoom lag luam metabolic kawg ntawm dopamine yog norepinephrine (noradrenaline).

DOPAC tuaj yeem oxidized los ntawm hydrogen peroxide, ua rau tsim cov tshuaj lom metabolites uas rhuav tshem cov tshuaj dopamine cia hauv cov vesicles hauv qhov tseem ceeb nigra. Qhov no tuaj yeem ua rau tsis ua tiav kev kho mob levodopa ntawm Parkinson' tus kab mob. MAO-B inhibitor xws li selegiline lossis rasagiline tuaj yeem tiv thaiv qhov no los ntawm qhov tshwm sim.

Biodegradation ntawm dopamine; Nws kuj tseem tuaj yeem pom hauv cov tawv ntoo ntawm Eucalyptus globulus.

Cov khoom no tau muab coj los ua ke (52% tawm los) los ntawm 4-Hydroxyphenylacetic acid ntawm aerobic biotransformation siv tag nrho cov kab lis kev cai ntawm tes ntawm Arthrobacter protophormiae.
