Add a coefficient to the single carbon atom on the right of the equation to balance it with the 3 carbon atoms on the left of the equation. c 3 h 8 + o 2--> h 2 o + 3co 2 The coefficient 3 in front of carbon on the right side indicates 3 carbon atoms just as the subscript 3 on the left side indicates 3 carbon atoms.
Tyrosine is an amino acid that is the foundational building block of dopamine. L-tyrosine is converted into levodopa which is, in turn, converted into dopamine. When tyrosine is taken at levels that are greater than what is possible from diet alone, central nervous system amounts of dopamine increase.
Stimulants comprise a large group of substances that include everything from the caffeine in coffee to illegal drugs such as crack cocaine and Amphetamines. Stimulants increase the amount of neurotransmitters in the brain. Neurotransmitters are the chemical messages that nerve cells send to each other to create sensations in the body. Dopamine is the neurotransmitter that is the most sensitive to the action of Stimulants. Dopamine is similar to adrenaline and affects brain processes that control movement, emotional response, and the ability to experience pleasure and pain.
