The good news: the U.S. is making a tectonic shift from burning coal to produce the majority of its electricity to using cleaner natural gas. The changeover produces less CO2, making electric cars cleaner across the country, roughly equivalent to a hybrid.
Dopamine is a neurotransmitter, a chemical responsible for sending messages between the brain and different nerve cells of the body. It's responsible for many functions, including memory, sleep, mood, pleasurable reward, behavior and cognition.
Dopamine is an organic chemical of the catecholamine and phenethylamine families that plays several important roles in the human brain and body, as well as elsewhere in biology. Its name derives from its chemical structure: it is an amine formed by removing a carboxyl group from a molecule of L-DOPA.In the brain, dopamine functions as a neurotransmitter âa chemical released by nerve cells to send signals to other nerve cells.The brain includes several distinct dopamine systems, one of which plays a major role in reward-motivated behavior.opamine itself is used as precursor in the synthesis of the neurotransmitter norepinephrine and the hormone epinephrine. Dopamine is converted into norepinephrine by the enzyme dopamine Î²-hydroxylase (DBH), with O 2 and L-ascorbic acid as cofactors.
