Dopamine is a neurotransmitter in humans and animals. It has a major role in reward-motivation. Dopamine is released into the brain in increased levels when “rewards” are completed. Several addictive drugs play on this like cocaine and amphetamine-based drugs. Outside the nervous system and the brain, dopamine does have some uses in the body like an inhibitor to norepinephrine in blood cells and increasing sodium excretion. Dopamine gets it’s name from it’s metabolite precursor, L-DOPA. Dopamine however cannot breach the blood/brain barrier, however it still is useful if it’s needed to be intravenously infected. In the body, it’ broken down by the enzyme monoamine oxidase via oxidation. However it can also be autooxidized by direct oxygen, resulting in quinones and free radicals. One of dopamine’s nicknames is the “pleasure chemical”.
