Low-density lipoproteins (ldl) are the principal transport vehicle for _____ in the blood.
aleksley [76]

Low-density lipoproteins (LDL) are the principal transport vehicle for cholesterol in the blood.

The body needs cholesterol, a waxy, fatty molecule, in the proper proportions for overall health. High blood cholesterol is a disorder that can result from unfavorable cholesterol levels. Low-density lipoprotein (LDL), also known as "bad" cholesterol, is the type of lipoprotein that carries cholesterol in your blood.

Cholesterol is primarily brought on by consuming fatty foods, failing to exercise regularly, being overweight, smoking, and using alcohol. Moreover, it can run in families. By consuming a healthy diet and increasing your physical activity, you can lower your cholesterol. Some folks also require medication. The majority of the cholesterol in your body is LDL (low-density lipoprotein), also referred to as "bad" cholesterol. Your risk of heart disease and stroke increases if your LDL cholesterol levels are high.
