Cholesterol

Cholesterol is a steroid substance, found in membranes and bloodplasma of all cells in mammals. It can also be found in other eukaryotes insmaller amounts, but prokaryotes don’t have any cholesterol.

Cholesterol is necessary to maintain adequate fluidity andmembrane permeability, and for synthesis of all steroid hormones in the body,bile acids and fat soluble vitamins, such as vitamins D, E, K and A. Recentstudies point out that cholesterol might be an important antioxidant in thebody.

There are different types of cholesterol present in the body, includingHDL (high-density lipoprotein),LDL (Low-density lipoprotein),VLDL (Very-low-density lipoprotein)and IDL (Intermediate-densitylipoproteins) cholesterol.

HDL is often called “good” cholesterol, since its main role is toreduce the quantity of LDL cholesterol in the plasma. It is always good to havenormal level of this type of cholesterol, and many people are advised toincrease HDL in order to minimize LDL effects to the human body.

LDL is so-called “bad” cholesterol. Increased LDL cholesterol usuallycause cholesterol accumulation in the walls of blood vessels, and lead toheart, arterial and vein problems. This type of cholesterol is necessary forour body, but is should be consumed in small amounts from the food.

Highlevel of cholesterol is one of the main indicators of many heart-relatedproblems, along with the atherosclerosis, stroke and peripheral vasculardisease. It doesn’t show any problems for a long time, but sometimes it maycause cholesterol buildup in the tendons and in the skin or other eye issues,like discoloration of cornea or yellow patches on the eyelids.
