Q: Question: Does iron bind to the Apo-B protein of low-density lipoprotein?
Answer: No binding was observed between iron, as a low molecular weight Fe(III) complex, and LDL. As a control albumin was able to bind iron, it seems evident that interaction of iron with LDL will involve other iron complexes.
A:
no
