![]() ![]() (b) In pinocytosis, the cell takes in small particles in fluid. phospholipid, also called Phosphatide, any member of a large class of fatlike, phosphorus-containing substances that play important structural and metabolic roles in living cells. The structure of hydrophobic paraffin chains varies from phospholipid to phospholipid and greatly. (a) In phagocytosis, which is relatively nonselective, the cell takes in a large particle. serve as major constituents for biological interfaces. The phospholipids are very important structural components of all cell membranes including those of the cell organelles. Phospholipids are a very important class of lipids containing phosphorous bound in a diester linkage. A single phospholipid molecule is made up of a phosphate group on one end, referred to as the 'head,' and two side-by-side chains of fatty acids, referred to as the 'tails. ADVERTISEMENTS: The below mentioned article provides an explanatory note on the structure of Phospholipids. \): The phospholipid bilayer of a cell membrane contains embedded protein molecules which allow for selective passage of ions and molecules through the membrane. Endocytosis is a form of active transport in which a cell envelopes extracellular materials using its cell membrane. A phospholipid is an amphipathic molecule, meaning it has both hydrophobic and hydrophilic components.
