Okay.
Sterol also.
And one of the biggest things that sterols, like cholesterol for us animals, does is provide shape and structure to our cell membranes.
Okay.
So cholesterol molecules are interspersed throughout all of our cell membranes, like the outside of our cells, which is called our plasma membrane.
And then also all of our organelles inside of our cells also have membranes that also have cholesterol within them.
And what this does is provide just the right amount of rigidity and structure without being like too solid.
Okay?
Cholesterol molecules are also moved back and forth across these cell membranes.
They interact with proteins, both inside and outside membranes, and they serve as signaling molecules that helps our cells communicate, like, within the cells, like between organelles, and then also between cells themselves.
Right.
Mm-hmm.
It's kind of a big deal.
Cholesterol does a lot of things.
It really does, because I'm not even done.
The backbone of cholesterol, those ring structures of carbons and hydrogens, are also the precursors to all of our steroid hormones.
So that's estrogen, testosterone, cortisol, all of them, and vitamin D, and our bile acids, which we learned in our gallbladder episodes, pretty freaking important.
So suffice to say...
We need cholesterol in order to be alive, right?
Totally.
