SciShow · 47,473 views · Added 2 months ago

AI Summary

This SciShow video explains how Tylenol (acetaminophen) is traditionally made from crude oil and explores cutting-edge research on using bacteria to convert plastic waste into this common painkiller. Learners will encounter chemistry and biology vocabulary such as 'polymer,' 'monomer,' 'bio-upcycling,' and 'biocompatible.' The video is great for practicing scientific explanation skills and understanding environmental innovation.

A lot more depends on fossil  fuels than you might expect.

00:03

Like your medicine cabinet. No, not the plastic pill bottles… the pills  themselves might be derived from crude oil.

00:08

Indeed, one of our most commonly-used drugs uses  a component of crude oil as a starting material.

00:13

And that drug is: Tylenol! Which is, by the way, safe and  effective, including during pregnancy.

00:19

Hence why it’s commonly-used. More than 15,000 metric tons are  produced globally every year.

00:24

Which means a lot of petroleum goes into  that needed, safe and effective pain relief.

00:29

Unless we didn’t have to use oil.. It is possible to recycle  plastic and turn it into Tylenol.

00:34

Not possible for us humans, though – we  need a hand from a pretty unexpected place.

00:39

[♪ INTRO]

00:42

Crude oil contains the starting chemicals  needed for a bunch of things you might not   think of, from shaving cream to paintbrushes,  clothing to fertilizers… and acetaminophen.

00:51

AKA Tylenol. Also called paracetamol outside the US.

00:55

We’ll just stick to calling  it Tylenol for this video,   though keep in mind we mean  the substance, not the brand..

00:59

See, Tylenol is made up of carbon,  nitrogen, oxygen and hydrogen.

01:03

But the thing about chemical synthesis  is that you can’t just pick out the   elements you want and stick them  together like building bricks.

01:09

There are only certain chemical  reactions that are physically possible.

01:12

To build up a molecule with an  oxygen here and a nitrogen there,   you need the right conditions  to achieve those reactions.
