A lipid bilayer is a thin polar membrane made of two layers of lipid molecules, which are amphipathic, meaning they have both hydrophilic (water-attracting) and hydrophobic (water-repelling) parts. This structure forms the fundamental framework of cellular membranes, allowing for the separation of the interior of cells from their external environment and facilitating various biological functions such as transport, communication, and energy transfer.
