WebA phospholipid is made up of a hydrophilic, water-loving, phosphate head, along with two hydrophobic, water-fearing, fatty acid tails. Phospholipids spontaneously arrange themselves in a double-layered structure with their hydrophobic tails pointing inward and their hydrophilic heads facing outward. WebNov 8, 2024 · One of the most prominent functions of PS is in blood coagulation, whereby its transport to the outer membrane layer in activated platelets is thought to either enhance the rate of prothrombin formation, or to allosterically alter the proteolytic and cofactor capabilities of prothrombin factors X a and V a in thrombin activation.
