Many complex multi functional group molecules are important in living organisms.

These large molecules pull water into the brain tissue after them by osmosis.

Many larger, complex molecules are just a bunch of smaller molecules bonded together

Can chemistry permit making these really large molecules where we've never been before?

Flat tiles

Particles

(In general, only large molecules, infectious agents, or insoluble foreign matter can elicit an immune response in the body.

Cerebral edema (swelling of the brain) occurs due to leakage of large molecules like albumins from blood vessels through the damaged blood brain barrier.

Well, we just said the ones that have the highest energy are the ones that are most likely to escape, the ones that have the highest kinetic energy.

It's just made up of a whole bunch of the molecules of the gas itself, and I'll draw each of the molecules with a little dot it's just going to have a bunch of molecules in it.

Inside the nucleus of the atom, we have particles upon particles when you smash them apart.

He called them partons. He called them partons.

Let me draw one of this guys molecules

He called them partons.

How the molecules are put together.

In fact, we are drowning in subatomic particles hundreds, thousands of subatomic particles every time we smash atoms.

These are not particles, but they behave like particles.

Molecules are competing for stuff.

Diatomic molecules are molecules composed of only two atoms, of either the same or different chemical elements.

A solution is sort of like a suspension of molecules where one type of molecule is blended or dissolved with another.

Antonio, they're dropping the big lights!

What we're left with is a whole bunch of molecules, and these molecules remain chemically the same whether they are by themselves or thrown together in a salad.

Molecules were represented using simple connectivity graphs

And the attraction, the forces, between the molecule and the protein cause the motion.

We now call these substances lipids.

We discovered they work by intermolecular forces alone.

Chemists are trying to study the molecules to look at disease.

So, let me draw the molecules that make up the surface

We can measure the masses of the particles, but we never really knew where this mass came from or why they have the masses they do.

Now molecules are really, really tiny.

These aren't even the skin cells themselves, these are the molecules that make up the skin cells.

All molecules are made up of atoms bonded together.

Right now I'm thinking of individual molecules.

Certain kind of molecules like to associate with the clay.

OK?

(Laughter)

And then you have other molecules, other complexes.

What's different is how the molecules are put together.

More particles.

I get it. Okay, so the molecules of the shake are the Higgs bosons!

Molecule A, you know, comes up and docks with this other molecule.

Scared of these students with their big brains and their big books and their big, unfamiliar words.

I know!

When particles travel in packs, the surface area is very small, and only the outside particles can collide.
