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.
Dopamine agonists such as pramipexole and ropinirole can be used as monotherapy to improve symptoms in early disease or as adjuncts to levodopa in patients whose response to levodopa is deteriorating and in those who are experiencing fluctuations in their response to levodopa.
