Autor: Naoki Terada, Shinjiro Hayakawa, Kenji Komaguchi, Katsushige Kouge, Hiromori Tsutsumi
Publikováno v: Analytical Sciences. 36:75-79
Insoluble sulfur (IS), used as a vulcanizing reagent of rubber, is prepared by the thermal ring-opening polymerization of sulfur (S8). Enhancing its thermal stability and content ratio (yield) is important for the industrial production of IS. The pos

Studies on Bitter Peptides from Casein Hydrolyzate. XIV. Bitter Taste of Synthetic Analogs of Octapeptide, Arg–Gly–Pro–Phe–Pro–Ile–Ile–Val, Corresponding to the C-Terminal Portion ofβ-Casein
Autor: Hideo Okai, Takashi Nakata, Katsushige Kouge, Masaru Nakatani
Publikováno v: Bulletin of the Chemical Society of Japan. 67:438-444
In order to elucidate the relationship between the chemical structure and bitter taste of the C-terminal portion of β-casein, some analogues, in which the phenylalanine residue was substituted by D-phenylalanine, lysine, glycine, glutamic acid or L-
