Phosphatitic
Phosphatitic refers to anything containing or relating to phosphate groups. In chemistry and biology, phosphate groups (PO4^3-) are crucial components of many molecules. The most prominent example is in phospholipids, which are essential building blocks of cell membranes. Phospholipids have a hydrophilic (water-attracting) phosphate head and a hydrophobic (water-repelling) fatty acid tail. This amphipathic nature allows them to form lipid bilayers, creating the barrier that encloses cells and their organelles.
Beyond membranes, phosphatidic acid is a key intermediate in the synthesis of all glycerophospholipids and triacylglycerols.
