Protein adsorption


The amino acid sequence is key to protein diversity


Due to properties of amino acid side chains (see handout) such as:

  • Charge
  • Polarity

Isoleucine is very hydrophobic

Arginine is very hydrophilic


The diversity of side chains and proportions of amino acids in each protein leads to diverse solubilities and surface interactions

Polar=hydrophilic, nonpolar=hydrophobic
