Lecithin is a major component of cell membranes. Lecithin is a phospholipid.
Proteins, carbohydrates, and lipids (including cholesterol and phospholipids) make up the majority of the plasma membrane. Intracellular components are shielded from the extracellular environment by the plasma membrane. The materials that enter and leave the cell are controlled by the plasma membrane, which mediates cellular functions.
Phospholipids, glycolipids, and sterols are the three kinds of amphipathic lipids that make up the cell membrane.
Lecithin is a general word for a class of amphiphilic, or water and fatty substance-attracting, yellow-brownish fatty compounds found in animal and plant tissues. They are used to smooth food textures, emulsify, homogenize liquid solutions, and deter adhering substances.
Functions : As an emulsifier, lecithin keeps fats and oils suspended and prevents them from combining with other substances. Lecithin supplements are available for a variety of medical conditions, including ulcerative colitis, high cholesterol, and as a lactation aid.
