Adsorption of L-amino Acids on Sea Sand
A study of adsorption of L-alanine, L-tyrosine, L-glutamic acid, and L-lysine on sea sand was carried out. Only L-lysine showed adsorption on sea sand, probably due to the presence of the positively charged R group. Our results raise some doubts as to whether sand was important for the pre-concentra...

| description | A study of adsorption of L-alanine, L-tyrosine, L-glutamic acid, and L-lysine on sea sand was carried out. Only L-lysine showed adsorption on sea sand, probably due to the presence of the positively charged R group. Our results raise some doubts as to whether sand was important for the pre-concentration of amino acids prior to peptide condensation on the Pre-Biotic Earth. |
