Ties on LDL surface is a key driving force for particle aggregation and fusion (18, 33, 39, 41, 52, 110, 111). The sturdy effects of solvent ionic conditions (pH, monovalent and divalent cations) indicate that electrostatic interactions are also critically involved (29). Electrostatic effects probably also contribute to various important processes in vivo, which include LDL fusion and coalescence into lipid droplets at acidic pH in deep atherosclerotic lesions or through lysosomal degradation (117, 118, 122, 135) or towards the effects of coronary artery calcium as a danger issue for atherosclerosis (136). Electrostatic effects in LDL aggregation, fusion, and lipid droplet formation also underlie laboratory solutions including LDL precipitation by magnesium salt, which can be a helpful tool to assess the patients’ threat of atherosclerosis (117, 118, 122, 135).OutlookVarious chemical and structural adjustments in the protein and lipid moieties promote LDL aggregation, fusion, and lipid droplet formation. It remains unclear which of those changes or their combinations are especially vital during atherogenesis. When these changesBiomol Ideas.

The genetic basis of these traits is just not well understood.
