Unit, Indian Inst. Sci., Bangalore 560 012, India). Int. J.Several substances like 57282-49-2 may be metioned in this study. Pept. Protein Res., 22(5), 617-21 (English) 1983. CODEN: IJPPC3.

The conformation and the aggregation of lysine mols. in the structure are similar to those in the crystal structure of L-lysine L-aspartate. A conspicuous similarity between the crystal structures of L-arginine acetate and I is that in both cases the strongly basic side chain, although having the largest pK value, interacts with the weakly acidic acetate group leaving the a-amino and the a-carboxylate groups to take part in head-to-tail sequences. Electrostatic effects are strongly modulated by other factors so as to give rise to head-to-tail sequences which are almost a universal feature of amino acid aggregation in the solid state. .
