The correct answer is High-Density Lipoproteins(HDL) cholesterol. EXPLANATION: Cholesterol: • It is produced in the body and builds a membrane around the cell in order to protect it. • It is a chemical compound that is waxy in nature. • The liver produces cholesterol, which is found in red fat meat, cheese, butter, and egg. • Lipoproteins help in the transport of these through the blood. Increased cholesterol levels are not good for health as it causes cardiovascular disease. • Cholesterol is insoluble in blood, it is transported in the circulatory system within lipoproteins. • There are several types of lipoproteins in the blood like very-low-density lipoprotein (VLDL), intermediate-density lipoprotein (IDL), low-density lipoprotein (LDL), and high-density lipoprotein (HDL). • LDL cholesterol is considered the bad cholesterol because it contributes to fatty buildups in arteries. This condition narrows the arteries and increases the risk for heart attack, stroke, and peripheral artery disease or PAD. • HDL cholesterol can be thought of as good cholesterol. So in the case of HDL cholesterol, higher levels are actually better. • HDL acts as a scavenger, carrying LDL (bad) cholesterol away from the arteries and back to the liver, where the LDL is broken down and passed from the body. • A healthy HDL cholesterol level may protect against heart attack and stroke. low levels of HDL cholesterol increase the risk of heart disease.
