HOW DOES SOAP INACTIVATE CORONAVIRUSES?
Hi, I'm Julie from the Exploratorium. You've probably heard that
washing your hands with............. and water is the most effective
way of preventing the spread of coronavirus. Now the question
is, why is soap so helpful? And the answer is due to the biology
and the structure of the
itself. Now a membrane
surrounds many viruses, including coronaviruses. And this
membrane is exactly the same as the one that surrounds our own
cells. The membrane is made of molecules that have a special
property. They have one side that I've represented in blue here,
that likes water, it's a water-loving end, and then their other half
of them dislikes water, it's a water-hating end. It likes fats a little
bit more. Now these molecules assemble so that they have
actually two ....... of them. One side lines up so the water's
facing on this end, and the other sidelines up so the water's
facing on that. And basically, a ribbon of these surrounds the
virus. Now the trick to Inactivating this virus is to disrupt the
membrane. Soap molecules have very similar
They
have one side that likes water, and another side that's attracted
to fat. That is why they're really helpful when you're washing
your greasy dishes. If you can get a soap molecule into the virus
membrane, it'll disrupt the structure of the membrane, and that
inactivates the virus. The other thing that soap is handy for, is it
can help us investigate the behavior of membranes. I have a tray
of soapy water here, and a string that I've threaded through two
straws. If you wanna try this at home, we have instructions and
a recipe for it on our website. You can see that when I pull up the
straws, that a film forms. This is a soap film. And this membrane
has the same behavior as the membrane around the virus. If​
