Synthetic Identification of Bitter Heptapeptide in Tryptic Hydrolysate of Casein
摘要:
A heptapeptide, H–Cly–Pro–Phe–Pro–Ile–Ile–Val–OH (1), was synthesized and found to be indistinguishable from the natural peptide (2), isolated from a tryptic hydrolysate of Hammersten casein by means of chromatography, amino acid analyses, and mass spectrometric measurements. Both peptides (1 and 2) have a strong bitter taste.
