WebWhat is a phospholipid? Type of lipid made from 2 fatty acid chain “tails” attached to a phosphate group “head”. Describe the phospholipid’s polar nature and how it interacts with water. Phosphate head group is polar and hydrophilic. Fatty acid chains tail is non-polar and hydrophobic. Thus, heads face water and tails point inwards ... WebMay 29, 2015 · Phospholipid is an amphipathic molecule — it has both hydrophobic and hydrophilic parts (this you understand very well). The hydrophobic part is a long chain of hydrocarbon (hence tail) whereas the hydrophilic part is a small but highly polar region (hence head). You should note that these parts are not disjoint but are covalently bonded. WebThe biological molecules known as phospholipids have a hydrophilic "head" region and a nonpolar, hydrophobic "tail." These forces cause the phospholipid molecules to aggregate together so that the polar heads are oriented towards the water and the hydrophobic tails are buried inside. The effect is to spontaneously establish a membrane. how dangerous is a heart cath
