Good and Bad Cholesterol...What is the different?
There are many false beliefs regarding good and bad cholesterol and their effects. Many people don’t know that cholesterol is mandatory for normal body functions. It becomes lethal only when it exceeds its normal level. But what exactly is cholesterol?
Cholesterol
Cholesterol is an organic waxy substance, classified as a steroid of fat. For the biosynthesis purposes it is used as a precursor of steroid hormones. Cholesterol is present in our body and performs many functions. It is essential for the proper development and maintenance of our cells and also controls the permeability of cell membranes. It supports the metabolism of fat-soluble vitamins, produces vitamin D in skin in the presence of sunlight and helps in the production of bile and hormones.
We derive cholesterol from foodstuff like meat, fish, eggs, milk, milk products etc. and it is also produced inside our body by the liver. Finally, cholesterol thus derived and produced enters into blood. As cholesterol molecules are insoluble in blood, certain protein substances called carrier lipoproteins help them to travel to the various parts of our body. Lipoproteins are a combination of lipids and proteins. They are able to carry cholesterol molecules to their target destinations.
