Human plasma lipoproteins and plasma proteins

Human plasma lipoproteins and plasma proteins represent a heterogeneous and complex group of biochemical entities essential for systemic homeostasis and the transport of endogenous and exogenous substances (StatPearls, 2023). Plasma proteins, such as albumin and various globulins, are critical for maintaining oncotic pressure and serve as the primary carriers for many pharmacological agents, significantly influencing drug pharmacokinetics and bioavailability (NCBI, 2022). Lipoproteins, categorized by their density (e.g., LDL, HDL, VLDL), are specialized macromolecular complexes that transport hydrophobic lipids, such as cholesterol and triglycerides, through the aqueous environment of the bloodstream (NIH, 2023). While this broad category is not a single therapeutic target, specific components within it are central to the pathology of cardiovascular and metabolic diseases. Therapeutic strategies often focus on modulating the levels or activity of specific lipoproteins to mitigate atherosclerosis risk or providing purified plasma proteins as replacement therapy for deficiencies (PubMed, 2021). Understanding the interaction between drugs and these circulating proteins is vital for predicting therapeutic efficacy and avoiding adverse drug-drug interactions (StatPearls, 2023).
