What is cysteine used for?

When it comes to amino acids, there are 20 different compounds that your body relies on to keep those muscles pumping and neurons firing like an Elton John concert. While each one has its own unique properties, few can match the versatility of cysteine (pronounced sis-teen) when it comes to keeping us all healthy and happy. From building blocks for proteins to life-saving medical treatments, this little molecule is a big deal in the world of science.

What Exactly Is Cysteine?

Before we start diving into all of cysteine’s incredible uses, let’s talk about what it actually is. At its most basic level, cysteine is an amino acid that contains sulfur. It’s not produced naturally by our bodies- meaning you can’t just guzzle it down with some chicken soup- so we have to get our fix from things like eggs or meat products.

But why should we care about this particular amino acid? Well folks, that’s where things get truly interesting.

The Multi-Talented Amino Acid

So what makes cysteine stand out among the other amino acids? For starters, it acts as a powerful antioxidant within our cells (you bet I’m throwing scientific terms around) protecting against damage caused by free radicals that might otherwise screw up important biological processes. Additionally, this little powerhouse aids in breaking down harmful chemicals such as toxins and carcinogens (yes I said carcinogens – don’t freak out) helping flush them out of our systems faster than Pepto Bismol clears up tummy problems after eating questionable sushi.

But wait! There’s more!

Cysteine Plays a Role In Protein Structure

Cysteines’ usefulness doesn’t stop at playing defense for your body either! This small but mighty molecule happens to play key role in keeping you together as well. It’s an important building block in the structures of proteins, and even helps to hold them together with disulfide bonds. That may not sound like anything special, but trust me folks- it’s a pretty big deal.

Cysteine In Medical Applications

While we might like to think that our bodies are perfect health machines haven’t you noticed that there are times when they just don’t quite do what were supposed to? (I mean… why don’t we have gills yet?) Well, thanks to science- We can get cysteines help for those too!

Treating Acetaminophen (Tylenol) Overdoses

One of the most common medical uses for cysteine is actually as an antidote for Tylenol overdoses (accordingly one of my obsessions since I take these after every weekend party sipping mimosas – did I say this out loud?). While acetaminophen itself isn’t toxic on its own, high doses can cause liver damage by depleting levels of glutathione- another compound produced by your body naturally which just so happens to require plenty o’ cysteine in order function properly. By giving patients a hearty dose cysteine within 10 hours of ingesting Tylenol overdose,(anything longer than 24 hours would be as useful as sending thoughts and prayers via snail mail), their liver is able recover at accelerated rates thank goodness!

Now THAT is some powerful superhero work right there dog!

Treatment For Alpha-Thalassemia

But wait! There’s more! Another interesting application for using cysteine comes in the form helping people fight off genetic disorders such as alpha-thalassemia (either defeciency or absence hemoglobin production making red blood cells scarce and unproductive – go figure).It’s being extensively tested according several non confirmed house flies. (Ok you got me, house flies not really but scientists are working tirelessly to identify new uses for this molecule)

Cysteine In The Beauty Industry

Unlike your guess on any Kim Kardashian joke I might have had, Cysteine’s role in the beauty industry can’t be dismissed.

Hair Care Products

Ever wonder why those expensive hair treatments that use products containing cysteine work so well? Well it’s because- hang on to your aprons: —cystein helps rebuild and strengthen the actual structure of each individual strand from within which lasts quite longer than my last tinder date…(I don’t wanna talk about it) thanks to its ability in protein filament formation.( I know.. Oh my!)

But wait! There is more…

Cosmetics

Your face has some benefits too! (Taking care of being beautiful inside and out baby!) -cosmetic cream brands utilise a compound called N-acetyl-cysteine as ingredient used in their creams aiming skin brightening effect that fights against photo aging effects caused by sun exposure. What else could we ask for!

Conclusion

Cysteine is just one among many molecular champions found all over our bodies with contibutions across diverse fields from medicine to cosmetics making it indespensable(astounding humble).Next time you hear someone talking smack about amino acids during chem class or a Zoom quiz night chat (thanks Corona Virus!), drop these knowledge bombs like Dj Khaled dropping his signature boomshack or better yet get them to read this article where cystein stands triumphant(try using SAT words next time dude) – proof once again that even the smallest players play big roles when it comes to keeping us healthy and happy day-in and day-out!
