![]() Lipids are molecules that include fats, waxes, and some vitamins, among others. This separation is essential for many biological functions, including cell communication and metabolism. 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. A phospholipid is a type of lipid molecule that is the main component of the cell membrane. represented in its phospholipid-bound form 160, high free myo. are attached to the basic phospholipid structure are shown in red. As a result, there are two distinct aqueous compartments on each side of the membrane. Download scientific diagram Phospholipid structures. The polar heads contact the fluid inside and outside of the cell.īecause of the phospholipds’ chemical and physical characteristics, the lipid bilayer acts as a semipermeable membrane only lipophilic solutes can easily pass the phospholipd bilayer. Thus, for monopolar, amphiphilic molecules such as phospholipids, it is possible to estimate the expected type of structure via a so-called packing parameter (P).
