They focus on the biochemical pathways that we find in humans, and they also take into account some physiological and clinical aspects. Glycerophospholipids, usually referred to as phospholipids (though sphingomyelins are also classified as phospholipids), are ubiquitous in nature and are key components of the lipid bilayer of cells, as well as being involved in metabolism and cell signaling. Phospholipids are a class of lipids that are important components of animal cell membranes, influencing the conformation and function of membrane-bound receptors and ion channels.

While free FAs (FFAs) are used as an energy source by both HSCs and progenitor cells (reviewed elsewhere 4), lipid metabolism is much broader, constituting a variety of metabolic pathways responsible for producing sphingolipids, glycerolipids, phospholipids and sterols (Figures 1 and 2). Understand that glycerol-3-phosphate is the substrate for the formation of both triacylglycerols and phosphoglycerols and that a branch point at phosphatidate leads to the synthesis of inositol phospholipids and cardiolipin via one branch and triacylglycerols and … CRC Crit Rev Microbiol. associated with other non polar constituents Cholesterol is an extremely important biological molecule that has roles in membrane structure as well as being a precursor for the synthesis of the steroid hormones, the bile acids, and vitamin D.
