What is phospholipods?

Phospholipids are a class of lipids that are a major component of cell membranes. They consist of two fatty acid tails and a phosphate group attached to a glycerol backbone, creating a hydrophobic (water-repelling) tail and a hydrophilic (water-attracting) head. This unique structure allows phospholipids to form bilayers, which serve as barriers that separate the interior of cells from their external environment. They play crucial roles in membrane fluidity, signaling, and the overall functionality of cells.
