Taste Receptors In Testes And Fertility
Geege Schuman stashed this in Science Too
Taste receptors have been found in in the stomach, intestines, pancreas, lungs, and brain, the researchers said. But, we really don't know what they are there for, study researcher Bedrich Mosinger, of the Monell Chemical Senses Center told Business Insider in an email:
"[The] function of taste receptors and signaling proteins outside of taste system is still unclear... [in some areas] they seem to be part of the chemical sensing of sugars or amino acids," he said. "For the most part, though, full function of these extra-orally located taste receptors is unknown."
New research, published today (July 1) in the journal Proceedings Of The National Academy of Sciences, found that these taste proteins for sweet and umami (the amino acid taste of soy sauce) not only exist in the testes, but they play an important role in mouse fertility.
All I can say is, there's no accounting for taste.
