Peptides. Part XXIV. Syntheses of the N-terminal pentapeptide and C-terminal tetrapeptide sequences of porcine gastrin

Abstract

Syntheses of derivatives of the peptide sequences L-pyroglutamylglycyl-L-prolyl-L-tryptophyl-L-methionine and L-tryptophyl-L-methionyl-L-aspartyl-L-phenylalanine amide required for the synthesis of porcine gastrin are described.
