<prompt> Lipids and proteins interact in membrane byHydrophobic interactionsBoth hydrophobic and covalent interactionsCovalent bondsH bonds  <response>: The proteins and Lipid molecules are held together by the non covalent interactions such as Vanderwalls forces which holds the hydrophobic tails together and hydrogen bonding which binds the hydrophilic heads with water which help to stabilize the liquid bilayer structure
