I’m sure there will be a bunch of teenagers who claim they can but it’s really not a thing. Your knackers can’t sense ‘taste’ in the traditional sense. Biology is remarkably cool, messy and utilitarian all at the same time. So, the same molecules sense taste in the mouth, have a role in sugar regulation in the gut and pancreas, play a vital role in spermatogenesis and likely a whole a bunch of other stuff. It was shown that if they are both absent the sperm just ain’t viable – and there were other problems evident with the testes too. When both the genes were knocked out the males were rendered impotent – and this is how the Plum Connection was discovered by accident.Īnyway, they discovered these two receptors play a key role in sperm maturation. They could breed knockouts for either but not both. So they looked harder and realised that female double knockouts were born fine, just no males. So they made knockout mice for each of the two genes and tried to cross-breed them. The study was trying to find out what happens if both the genes TAS1R3 and GNAT3 are absent. Why you need sugar sensors in your arsehole remains unclear.īasically the first one is a receptor for sweet, salty and ‘umami’ flavours, it then gets the second one all jiggy – which is plays a big part in mediating basic taste.
It turns out TAS1R receptors are all over the place: in gut cells and pancreatic cells where they contribute to nutrient sensing and regulation of glucose metabolism, and also in your Chocolate Starfish. So, ‘taste receptors’ not just in your mouth but in your knackers as well? And sperm can taste stuff? Crikey. They are also strongly expressed in testis and sperm, but their functions in these tissues were previously unknown.
TAS1R taste receptors and their associated heterotrimeric G protein gustducin are involved in sugar and amino acid sensing in taste cells and in the gastrointestinal tract.
Really? This story dates back to a 2013 paper in – appropriately – PNAS which found: It’s everywhere, especially on TikTok – which I’d never heard of until today.Īpparently if you dangle your Love Spuds in a sweet or salty liquid you can actually taste it. Remember the Tide Pod Challenge?Īnyway, something going viral at the moment is teenage boys teabagging soy sauce. The difference is nowadays social media can propagate stupidity – especially amongst the yoof – faster than shit through a goose. I did some pretty dumb shit when I was a teenager.
