WebJan 26, 2024 · Liposomes are well-recognized and essential nano-sized drug delivery systems. Liposomes are phospholipid vesicles comprised of cell membrane components and have been employed as artificial cell models to mimic structure and functions of cells and are of immense use in various biological analyses. Liposomes acquire great … WebSince phospholipids are the main components of the biomembrane, phospholipids vesicles are widely employed to mimic the metabolic function of cellular structures. Herein, we describe recent developments in the construction of phospholipid vesicles as artificial cells, together with the applications of these vesicles.
Phospholipid synthesis occurs in the cytosolic side of ER membrane that is studded with proteins that act in synthesis (GPAT and LPAAT acyl transferases, phosphatase and choline phosphotransferase) and allocation (flippase and floppase). Eventually a vesicle will bud off from the ER containing phospholipids destined … See more Phospholipids are a class of lipids whose molecule has a hydrophilic "head" containing a phosphate group and two hydrophobic "tails" derived from fatty acids, joined by an alcohol residue (usually a glycerol molecule). … See more Diacylglyceride structures See: Glycerophospholipid • Phosphatidic acid (phosphatidate) (PA) • See more Computational simulations of phospholipids are often performed using molecular dynamics with force fields such as See more Common sources of industrially produced phospholipids are soya, rapeseed, sunflower, chicken eggs, bovine milk, fish eggs etc. Phospholipids for gene delivery such as See more Arrangement The phospholipids are amphiphilic.
