VLDL are precursors of LDL

Very low density lipoproteins are precursors of atherogenic LDL. The VLDL that are formed in the liver are detrimental to the body when they are stripped of their triacylglycerols by extra-hepatic tissues (Figure 4). The remnants, which are cholesterol rich, are low-density lipoproteins, LDL. LDL are the main source of cholesterol deposition in peripheral tissues. Protecting against the ill effects of high cholesterol levels therefore requires targeting VLDL formation, a precursor to LDL (Nelson and Cox, 2004).

TQ, Maggie Danhakl,
The visual representation on the effects of high cholesterol is indeed informative and useful for our students. I have included it here and shared it on my Facebook.
