What specific biological molecule (i.e., protein, nucleic acid, lipid, carbohydrate, or vitamin) is affected by this disease (be sure to provide the specific name of the molecule)? 

Gamma-aminobutyric Acid (GABA) is the specific biological molecule that has been affected by this condition. GABA is an inhibitory nervetransmitter which plays a key role in the regulation of nerve cell activity. People with depression or other mood disorders may have reduced levels. It could also be affected by changes in receptor sensitivities and/or altered levels of the enzymes that are involved in GABA synthesis. GABA acts by preventing certain neurons firing off. If too many neurons get activated it causes anxiety and racing thoughts. Studies have shown that medication targeting these receptors could help alleviate symptoms of schizophrenia, depression and bipolar disorder. The exact mechanisms of this phenomenon are still unknown, so further research is necessary to find more effective treatment options. This demonstrates how vital this particular molecule can be in maintaining an emotional balance within the body.
