The Cretaceous period is the last period of the Mesozoic area where new groups of mammals, birds, and flowering plants appeared on Earth.
The primary driving force that stabilizes lipid bilayers is the formation of hydrophobic bonds between fatty acid chains in phospholipids and protein.
The cell membrane is made up of phospolipid bilayer with proteins embedded in between
Lipid bilayer is the structure present in the biological membrane. It consist of two layers of lipids with hydrophilic end facing each other and hydrophobic end facing the outer side.
the inner layer has both the hydrophobic end of the lipid molecules facing each other and bonded by hydrophobic bond van der waals forces.
The outer molecules are bonded with the protein molecules through hydrophilic bonds called hydrogen bonds.
