Weak chemical forces hold together the structure of membranes. A membrane is formed by lipid bilayers. The layers have a hydrophilic and hydrophobic area. The hydrophobic area on both layers face towards each other and to form the hydrophobic area, while the hydrophilic heads of the layers face outwards. Van der waals forces become present when the hydrophobic dipoles interact with each other. Ionic bonds are important for creating the cells shape, by creating different shapes of proteins. The membrane structure is held together by the peptide bonds of proteins through hydrogen bonding.
The alpha-helix region of a protein that goes through the membrane is hydrophobic when it is within the membrane because it is passing through the hydrophobic
