So this is two different things . So saturated fat consumption in many people will raise LDL cholesterol . So it's important to differentiate between the what what is saturated fat .
Virtually . All of that is the cholesterol we produce , that gets taken back to the liver that the liver packages in bile and secretes . So that's , that's what aids in our digestion , which is another thing I should have mentioned earlier .
The cholesterol you eat is esterified and , and a ster cholesterol molecule simply can't physically pass through that Nieman Pixie one like one transporter . Now we probably manage to destery 10 to 15% of our dietary cholesterol . So in other words , there are small amounts of dietary cholesterol that do make their way into our circulation , but it represents a small fraction of our total body's pool of cholesterol .
It also has to accommodate having porous structures that traverse its membrane to allow ions and things like that to go across . And it's cholesterol that gives the fluidity to that membrane . It's also as you're alluding to the backbone of some of the most important hormones in our body , estrogen , progesterone testosterone , cortisol .
