What are blood lipids?

lipid can be basically defined as a substance that is insoluble in water, but is soluble in alcohol or other type of solvent. Blood lipids are lipids or fats in the bloodstream. Some commonly known blood lipids are cholesterol, cholesterol complexes and triglycerides. These molecules may be freely found in the blood, although they are most often packed and transported in protein complexes. The liver is basically responsible for ensuring that all tissues receive enough lipids for proper functioning and normalization of blood lipid concentrations. In the liver, triglycerides and cholesterol are wrapped in complexes of various densities or lipoproteins and then released into the bloodstream.

There are three commonly known lipoproteins. The very low density of Lipoproteins (VLDLS) consists mainly of triglycerides, but eventually become lipoproteins with low density (LDL). The main component of LDL is cholesterol and high LDL levels are associated with a higher risk of heart disease. LipoproHigh -density Teins also consist of cholesterol, but also contain a large amount of protein and seem to serve as gadgets by cleaning excess cholesterol from the blood. Unlike LDLS, the high proportion of HDL in the bloodstream is associated with a protective effect against the development of heart disease.

The

hypothesis of lipids was first developed in the 1950s to describe the link between high levels of cholesterol in blood and heart disease. This hypothesis is now accepted by many scientists and doctors who claim that years of scientific research have confirmed this association, but a strong minority does not agree with the mainstream view. Lipid hypothesis opponents claim that less than half of patients with a heart attack have high cholesterol levels and many suggest that inflammatory guilt processes for heart disease than blood lipid levels.

Given the generally wide acceptance of the lipid hypothesisIt often recommends that people over 20 years old get a lipid profile in their blood. This profile measures LDL, HDL and triglycerides and is a simple blood test that should be drawn after a 12 -hour fast. Fast ensures that lipids obtained from the diet were cleaned from the bloodstream.

Although blood lipids are usually displayed in negative light, they have many important features in a healthy body. They are necessary for the formation of cellular membranes and are the main form of storage of the body of the body. In addition, lipids are processed in the body to become basic hormones.
