What is a pholosipid made of?

A phospholipid is composed of two fatty acid tails, a glycerol backbone, and a phosphate group. The fatty acid tails are hydrophobic (water-repelling), while the phosphate group is hydrophilic (water-attracting). This unique structure enables phospholipids to form bilayers, which are fundamental components of cell membranes, allowing cells to maintain their integrity and control the movement of substances in and out.
