What is formed from VLDL as triglycerides are broken down?

• A. HDL
• B. Chylomicrons
• C. LDL
• D. Deaminated molecules

Answer: (C)

When very low-density lipoprotein (VLDL) particles circulate in the bloodstream, they serve the purpose of transporting triglycerides, which are a type of fat, to various tissues for energy or storage. As VLDL delivers triglycerides to peripheral tissues and undergoes enzymatic action, particularly by lipoprotein lipase, it gradually transforms.

During the breakdown and loss of triglycerides, the VLDL particles become smaller and denser. This process ultimately leads to the formation of low-density lipoprotein (LDL). LDL is rich in cholesterol and contains a lower proportion of triglycerides compared to its precursor, VLDL. The primary role of LDL in the body is to deliver cholesterol to cells, which is important for various physiological functions, including membrane structure and hormone synthesis.

In contrast, the other options represent different types of lipoproteins or molecules with distinct functions. HDL (high-density lipoprotein) is known for its role in reverse cholesterol transport, while chylomicrons are responsible for transporting dietary lipids from the intestines. Deaminated molecules do not pertain to lipid metabolism as they are typically associated with the breakdown of amino acids. Thus, the correct answer reflects the metabolic pathway where VLDL
