Final answer:
Low-Density Lipoproteins (LDL) and Very-Low-Density Lipoproteins (VLDL) are types of lipid transporters in the body. LDL, often termed "bad" cholesterol, transports cholesterol to tissues, and VLDL carries triglycerides. In contrast, High-Density Lipoproteins (HDL) are "good" cholesterol transporters, removing cholesterol from tissues.
Step-by-step explanation:
Low-Density Lipoproteins (LDL) and Very-Low-Density Lipoproteins (VLDL) are types of lipids in the body that play essential roles in transporting fats, including cholesterol. LDL is often referred to as the “bad” cholesterol transporter because it carries cholesterol from the liver to other tissues in the body, potentially leading to the accumulation of arterial plaques. VLDL primarily carries triglycerides and is also considered a “bad” cholesterol transporter for its role in plaque buildup.
On the other hand, High-Density Lipoproteins (HDL), sometimes known as the “good” cholesterol transporter, are responsible for carrying cholesterol from body tissues back to the liver, where it is either reused or excreted. Maintaining a balance of low LDL and high HDL levels is crucial for reducing the risk of heart disease. As such, for healthy total blood cholesterol, maintaining an LDL level under 100 mg/dL and an HDL level above 40 mg/dL for men and 50 mg/dL for women is ideal.
