Answer:
Phospholipid,
proteins;
Sterols and oligosacharides,
Step-by-step explanation:
Phospholipid: Phospholipid tails can be saturated or unsaturated, those which have double bonds are unsaturated phospholipds, which have only single bonds are called saturated fatty acids. They are found in both inner (PS) and outer membrane(PC).
Proteins: i) Intergral protein: which are integral part of plasma membrane,
ii) Peripheral proteins: which are found on the periphery of both outer and inner membrane.
Sterols; are found in both ,inner and outer membrane.
