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 Link to ADHD and Obesity. Different studies have hypothesized about the link between obesity and ADHD.

Researchers Benjamin Charles Campbell and Dan Eisenberg (2007) note that dopamine levels in the brain increase when food is present, even if the person does not eat it.
