Answer 1

Low-density lipoproteins (LDLs) can contribute to the build-up of plaque that narrows blood vessels; however, LDLs are necessary because they are used to synthesize  eicosanoid

Explanation:

The article eicosanoid is practiced to include those biologically effective lipid intercessors obtained essentially from C20 fatty acids. The 'actual' eicosanoids are provided enzymatically with high stereochemical accuracy, and this is necessary for their biological purposes.

Biosynthesis of eicosanoids concerns the progress of multiple enzymes. Eicosanoids are produced largely from unesterified fatty acids, no the CoA esters, and they work in this kind, but it is frequently noticed that they may transpire and some may admittedly be incorporated while esterified to other lipids.
