The lipids associated with very low density lipoprotein
1. are usually linked covalently to apoproteins.
2. belong primarily to the phosphatidylcholine class.
3. incorporate fatty acids that are synthesized in the liver.
4. reflect, in general, the types of lipids found in the diet.
Biochemistry
Answer: 3
VLDL is a lipoprotein particle synthesized in the liver and secreted into the bloodstream to transport endogenously synthesized triglycerides and cholesterol to peripheral tissues. The triglycerides in VLDL are derived from fatty acids synthesized in the liver, and the cholesterol is derived from both dietary sources and de novo synthesis in the liver. They are not usually linked covalently to apoproteins (Answer 1), nor do they primarily consist of phosphatidylcholine (Answer 2). While the types of lipids found in the diet (Answer 4) can influence the liver's synthesis of VLDL, the statement does not accurately describe the direct composition of VLDL.
