The polar amino acids
WebbA typical membrane-spanning segment consists of 20-25 hydrophobic amino acids arranged in an alpha helix, although not all transmembrane proteins fit this model. Some integral membrane proteins form a channel that allows ions or other small molecules to pass, as shown below. WebbC. Non-polar amino acids are found in the interior of the protein. A major driving force for protein folding is the burying of non-polar amino acids in the interior of the protein to …
