Abstract
|
|
|
|
To elucidate adsorption of proteins and examine the molecular behavior of protein molecules at interfaces, various proteins at the air-water interface were studied. The adsorption data of bovine serum albumin intermediates indicated that the conformational state of a protein played an important role in adsorption of proteins at interfaces. The adsorption behavior of succinylated beta-lactoglobulin indicated that the increase in the net negative charge of the protein significantly inflenced both the kinetics and thermodynamics of adsorption. The adsorption kinetics of beta-casein showed that the salt that induced break-down of water structure decreased the rate of adsorption.
