The main components of blood lipids

Blood lipids, as the name suggests, are actually lipid substances in the blood, which are divided into two categories: neutral fats and lipids. Cholesterol belongs to lipids. One of the three high blood lipids we usually talk about is high blood lipids. High blood lipids will increase the incidence of cardiovascular and cerebrovascular diseases, especially thrombotic diseases such as cerebral infarction. If you want to lower blood lipids, you must understand the composition of blood lipids. Only by taking the right medicine can you get immediate results. Let me introduce it to you below.

Overview

Blood lipids are the general term for neutral fats (triglycerides) and lipids (phospholipids, glycolipids, sterols, steroids) in plasma, and are widely present in the human body. They are essential substances for the basic metabolism of living cells. Generally speaking, the main components of blood lipids are triglycerides and cholesterol. Triglycerides are involved in energy metabolism in the human body, while cholesterol is mainly used to synthesize cell membranes, steroid hormones and bile acids.

composition

All blood lipids are combined with proteins to form lipoproteins. The basic structure of lipoprotein is a core of triglycerides with varying contents, surrounded by a layer of phospholipids, cholesterol and protein molecules. Lipoproteins are divided into chylomicrons CM, very low-density lipoprotein VLDL, low-density lipoprotein LDL, and high-density lipoprotein HDL according to their density. The main carriers of triglycerides are chylomicrons and very low-density lipoproteins, and the main carriers of cholesterol are low-density lipoproteins and high-density lipoproteins.

cholesterol

source

300-500 mg is absorbed directly from food every day. The body synthesizes 1g every day, 70-80% comes from the liver and 10% comes from the small intestine. Carried by low-density lipoprotein and transported throughout the body.

Way out

Used to synthesize lipid hormones; form cell membranes, etc. High-density lipoprotein absorbs excess cholesterol in tissues, transports it to the liver, and is processed into bile acid for excretion from the body.

adjust

In a normal human body, the sources and destinations of triglycerides in the blood are basically balanced. Generally regulated by high-density lipoprotein.
