Effect of iron (III) hydroxide sol as a support for oligomerization of l-phenylalanine in aqueous solution

An oligomerization of l-phenylalanine in aqueous solution was studied in the presence of iron (III) hydroxide sols. Adsorption study of l-phenylalanine indicated that assemblies of l-phenylalanine onto the iron hydroxide sols were predominant factor to improve the yield of the oligomerization product.
