The recycling of LDL cholesterol is driven by the demand for the originating cargo, which is delivered by VLDL particles.

“the demand is for the cargo the originating cargo that is clearly getting used right but we agree the VLDL vanishes very quickly the VLDL remodels to LDL very quickly yes but if you go through the kinetics of this I can't follow why he should still have that much LDL cholesterol unless he is making more cholesterol in other words I've tried to think of this ten ways to Sunday the only way on a mass balance that I can explain this hypothesis is if he's making more cholesterol and not if he's recycling the same cholesterol like certainly he's making more relatively isn't only if he were depleting it in some other store”
