Lecithin is a type of phospholipid found in biological membranes. Phospholipids consist of a hydrophilic (water-attracting) ”head” and two hydrophobic (water-repelling) ”tails,” forming the lipid bilayer of cell membranes. Lecithin, specifically, contains glycerophospholipids, which are essential for maintaining the structure and fluidity of the membrane. It also plays a role in emulsification, making it crucial in biological and industrial processes.
