So, let's talk about the transport function, about cholesterol.We'll have a whole lesson on cholesterol.But, I have to tell you, there is good cholesterol (high-density lipoprotein - HDL).Cholesterol is generally insoluble in water and therefore insoluble in blood.And for it to be there, this fat (cholesterol), it is combined with a transport protein (lipoprotein).And if there is a lot of this transport protein, then there is no atherosclerosis.The more HDL in your lipid profile, the calmer you should feel.What is bad cholesterol?He is not good or bad.In terms of its chemical structure, it is the same, but the ball itself, low-density lipoprotein (LDL), is fundamentally different from the safe one.Because the squirrel in it, the cat cried.Because we don’t understand and listen to the doctor, but the doctor says: “Don’t eat meat, or only meat that contains little fat.Please eat one egg or two eggs a week because they contain a lot of cholesterol.Well, of course, everything is low-fat.”And it turns out that it seems like there should be less of this fat, but in fact it’s exactly the opposite.If a person does not eat enough protein, which is always friends with fats, we will understand this in the next lesson, then he is forced to catch up with something - starches.I want to eat something.And I will show you the mechanism of how excess glucose is made from starches, and ultimately LDL is a lot of fat and just a little bit of protein.
The next function is very important - construction.We can use the example of vessels.Look, all the girls with high blood pressure and low blood pressure, with varicose veins, now I will tell you your mechanism.The heart contracts and pumps blood through the arteries, and the arteries distribute blood flow to all organs and systems, and there must be powerful pressure in the arteries in order for the blood to be transferred to the organs.What do we need for this?How did God organize the artery?And he organized it in three layers.Inside, the endothelium is a thin layer, one delicate layer of cells.This layer is very easy to damage, but we are not going to do that.Above it are elastic fibers, because the artery must be elastic.If it corrodes, then no one will receive oxygen and nutrients.
Next comes a thick layer of smooth muscle.This is to maintain normal flow, normal blood pressure.The outer layer is dense connective tissue.So, our girl heard that fats are harmful, and fats are always friends with proteins, and in general there is a lot of cholesterol in these protein products.And I decided to eat salads.And now she’s been on salads for a month, two on salads.I'm hungry, so I added more starch.And the muscle membrane, it must be built from something, and not from what.Protein is only enough for the brain, heart, and liver, because try not to make enzymes and hormones, but this membrane is not enough.And it turns out that our girl, when she lies down, everything seems to be fine, the heart contracts, and the blood reaches the brain horizontally.Everything is fine.As soon as the girl stood up suddenly, it was immediately dark, as if the lights had been turned off.This is such an unfinished thick layer of smooth muscle.You can't even call him fat.Some layer of smooth muscle.The person has changed the position of the body, the heart has contracted, but the blood does not reach the brain through the sluggish arteries.This happens.This is called hypotension.They say: “Oh, I have low blood pressure, I’m hypotensive.”
