There are two groups of bases: Pyrimidines: Cytosine and Thymine each have a single six-member ring.
Tastes associated with caffeine, quinine, or aspirin are detected primarily
by bitter taste receptors.
These receptors can either be TAS2Rs or T2Rs and they help to protect
against harmful food substances. They are also responsible in the
stimulation of hormones which increases hunger.
Bitter taste receptors are found in the oral cavity and stomach and it is the
receptor which bind to more than fifty percent of all the drugs
manufactured.

Answer:
Ghrelin is made in the stomach. It stimulates hunger by entering the brain and acting on the neurons in the hypothalamus to increase the activity of the hunger-causing nerve cells and reducing the activity of hunger-inhibiting cells. As the stomach empties, the release of ghrelin increases. Our hunger is influenced not only by our physical state but also by our memory of when we last ate and our expectation of when we should eat again. And although we humans as a species prefer certain tastes (such as sweet and salty), we learn to satisfy those preferences with specific foods eaten in the context of our families and our culture. Some of our taste preferences, such as the avoidance of new foods or of foods that have made us ill, have survival value.
