On the right, fluorescently marked epidermal lysosomes (top), intestinal lysosomes (middle), and lipid droplets (bottom) highlight the organelles engaged in lysosome-dependent lipid degradation. Together, the image visualizes a microbiota–lysosome axis through which bacterial tryptophan metabolism reprograms host lipid homeostasis. Image Credit: Kenan Zhang

Scientists found tryptophan, the ‘sleepy’ amino acid, in an asteroid. Here’s what it means An essential amino acid that is mistakenly believed to cause drowsiness after eating turkey has been found in an asteroid for the first time, giving scientists clues to the origin of life on Earth.

I find this interesting. First off, no, #Bennu is NOT a giant #spaceturkey despite them finding #tryptophan!

But that it has so many amino acids present does suggest that the building blocks of life were not that rare in the early solar system. That's pretty cool!

Thanksgiving turkey and tryptophan don't make you sleep The Thanksgiving turkey tryptophan myth suggests that turkey causes sleep is not supported by science. Blame the mashed potatos.

The Thanksgiving #turkey #tryptophan causes sleep myth is well-known. However, research shows turkey contains similar tryptophan levels as other meats, and it doesn’t impact sleep directly. Blame the carbohydrates.

Huge Trypto-fan!* *Contrary to popular belief, turkey does not contain significantly more tryptophan than other common meats, and it isn't what causes your food coma!

It's time for my annual reminder that turkey does NOT contain more #tryptophan than other meats, and the molecule is not the cause of your food coma!

Nevertheless, I hope this #science pun is enough to drive you off your screens for some well-deserved relaxation.

Happy Thanksgiving!
