Which statement best describes the relationship between VLDL,IDL,and LDL?
A)VLDLs are rich in triglycerides,but when acted on by lipoprotein lipase,they are converted into IDLs,which in turn are converted into cholesterol-rich LDLs.
B)VLDLs are rich in triglycerides,but when acted on by pancreatic lipase,they are converted into IDLs,which in turn are converted into cholesterol-rich LDLs.
C)VLDLs are rich in triglycerides,but when acted on by lipoprotein lipase,they are converted into LDLs,which in turn are converted into cholesterol-rich IDLs,which are returned to the liver.
D)VLDLs are rich in cholesterol,but when acted on by lipoprotein lipase,they are converted into IDL,which in turn are converted into triglyceride-rich LDLs,which are returned to the liver.

Question

Quizplus · Accepted Answer

VLDLs are produced by the liver and contain mostly triglycerides. When acted on by lipoprotein lipase, they are converted into IDLs, which contain a mixture of cholesterol and triglycerides. Further action of lipoprotein lipase on IDLs leads to formation of LDLs, which are primarily cholesterol-rich and are taken up by cells through LDL receptors. Therefore, statement A is the best choice as it accurately describes the sequence of conversion from VLDLs to IDLs to LDLs.
