Studies of the dissolved organic compounds in the sea - A preliminary report on the isolation, separation and identification of free amino acids

Abstract

A method of concentrating and desalting sea water using evaporation and ion exchange techniques is described. Circular paper chromatography has been used to separate and identify free amino acids in desalted concentrates of sea water from three different localities along the Norwegian coast. The following amino acids have so far been identified: cystine, lysine, histidine, arginine, serine, aspartic acid, glycine, hydroxyproline, glutamic acid, threonine, α-alanine, proline, tyrosine, tryptophan, methionine, valine, β-phenylalanine, isoleucine and leucine.
