title: Studies on gliadin related peptides. I. Synthesis, purification and 1H n.m.r. characterization of the pentapeptide H-Tyr-(Gln)3-Pro-OH.
abstract: The pentapeptide H-Tyr-(Gln)3-Pro-OH has been recently postulated to be the basic repetitive unit of a sequential polypeptide contained in wheat bread alpha-gliadins, which are believed to be toxic factors in coeliac disease, gluten-dependent enteropathy. Solid-phase synthesis, purification and 1H n.m.r. characterization in water solution of this peptide are described.
