cis Fatty acids Trans Fatty acids Saturated Fats Optimal level
LDL 103 117 121 <100
HDL 55 48 55 >40
LDL-to-HDL ratio 1.87 2.43 2.2 <2

Introduction:

Lipoproteins are the assembly of proteins and lipids, which serves the purpose of transporting lipids (mainly cholesterol) in the blood or extracellular fluid. These have phospholipids on the exterior while other lipids in the interior. Phospholipids are so oriented that the hydrophilic part is on the outer side while the hydrophobic part is on the inner side.

The metabolic pathway below is used for the production of the purine nucleotides adenosine monophosphate (AMP) and guanosine monophosphate (GMP) in eukaryotic cells. Assume each arrow represents a reaction catalyzed by a different enzyme. Using the principles of feedback inhibition, propose a regulatory scheme for this pathway that ensures an adequate supply of both AMP and GMP, and prevents the buildup of Intermediates A through G when supplies of both AMP and GMP are adequate.
