cholesterol is a lipid it is synthesized by every cell in our body that means every cell in our body makes cholesterol okay so why do we make this stuff well this stuff is super important or every cell in our body wouldn't make it it's essential for the creation of a cell so a cell you know when you look at cells when you look at a picture of a cell in a you know in a book or online or something they look like two-dimensional structures right they're sort of these flat things but really that's not what cells look like that's kind of a cut open cell projected onto 2d the reality is cells are three-dimensional and they have to be able to be more than just perfectly open spheres so what gives them that fluidity is their membranes and it's the cholesterol within the membrane that provides that fluidity it's also what allows transporters to go across the surface of cells these transporters are what allow various things like glucose ions hormones etc to traverse cell membranes
