Membrane lipids under norm and pathology
(Wydawnictwo Uniwersytetu Rzeszowskiego, 2021) Marzoog, Basheer Abdullah; Vlasova, Tatyana Ivanovna
Introduction. Lipid is an essential component of the cell and its organelles membrane. The uniqueness and selectivity of lipids to specific functions and asymmetry of lipid distribution in the organelle’s membrane give the cell ability of being highly qualified and specified. Aim. The paper provides a comprehensive review of membrane lipids in different tissues and organelles of the cell in norm and disease. Material and methods. The paper analyzed the present literature data on membrane lipids behavior in physiology and pathology. Analysis of the literature. The major structural and functional lipids of the cell membrane are phosphatidylcholine > phosphatidylethanolamine. The absence/deficiency or augmentation of a specific type of lipid results in serious defects and usually life-threatening with a permanent disability. The observations discussed here suggest, the lipid peroxidation severity depends on the membrane lipid composition of the cell. Some tissue cells can handle lipoperoxidation and protect themselves from the peroxidation damaging products better, while other cells cannot compensate. Therefore, some organs are highly sensitive to peroxidation and irreversible changes occur rapidly. Conclusion. To sum up, the understanding of lipid’s role in norm and disease is clinically crucial to evaluate a novel therapeutic target to treat many metabolic disorders such as metabolic syndrome and some lysosomal storage disorders via targeting specific new signaling pathways, lipid molecules, and enzymes.
