My name is César Ramirez-Sarmiento. I'm based in Santiago, Chile.

00:08

I'm a protein engineer and designer. Proteins are macromolecules which are composed of amino acids.

00:15

They are made of 20 different types of amino acids.

00:17

They are represented by letters. So you can imagine an alphabet of amino acids, and you can imagine that these amino acids are connected to each other like beads on a string.

00:27

And so that allows for them to come together in different geometries.

00:31

And so they get a shape, they get a three-dimensional structure that allows for them to dictate their functions.

00:38

We have many different proteins with many different shapes that actually perform different biological functions in cells.

00:44

They allow us to digest food, they allow us to transport ions for electrical signals to go through neurons.
