    Notes: From time to time, A.I.Ch.E. Journal presents translations of certain technical articles written by our Japanese colleagues in their own language. These translations are made by Kenzi Etani, who received his B.S. in chemical engineering in 1953 at the Tokyo Institute of Technology and his M.S. in 1955 at M.I.T. He is associated with Stone & Webster and is an associate member of American Institute of Chemical Engineers. He is also a member of the Society of Chemical Engineers, Japan, and the Japan Oil Chemists' Society. His offer to help break down the language barrier is acknowledged.Abstracts, notation, literature cited, tables, and figure captions not published here appear in English in the original paper. No figure will be reproduced in these translations.The following article was published in Chemical Engineering (Japan), 21, pages 17-25 (1957).

    Notes: Molecular mechanics calculations have been performed for the disaccharide carrabiose, one of the repeat units of β-carrageenan, as a general model for the (1→4)-linkage in the carrageenans. An adiabatic conformational energy map for this unsulfated molecule was prepared by constrained energy minimization and compared to a previously reported rigid-residue energy map for the sulfated molecule and to a similar adiabatic map for neocarrabiose, the related (1→3)-linked dimer repeat unit of β-carrageenan. Molecular dynamics simulations of this molecule in vacuo and in an aqueous (TIP3P) solution were calculated, and the observed motions were found to be generally consistent with the vacuum adiabatic energy map. Unlike the case observed in previous simulations of neocarrabiose, little salvation shift in the molecular conformation was observed for carrabiose. From the dynamics, the linkage was observed to be relatively flexible, as has been inferred from experiment on sulfated carrageenan polymers. © 1997 John Wiley & Sons, Inc.

    Notes: Molecular mechanics calculations have been performed for the disaccharide neocarrabiose, one of the repeat units of β-carrageenan, as a general model for the (1 → 3)-linkage in the carrageenans. An adiabatic conformational energy map for this molecule has been prepared by constrained energy minimization and compared to previously reported relaxed maps. Neither the experimentally determined crystal structure of neocarrabiose nor the fiber diffraction conformation of β-carrageenan is a low energy conformation on the relaxed Ramachandran map. Molecular dynamics simulations in vacuum produced trajectories consistent with this relaxed vacuum surface. However, a simulation with explicitly included solvent water molecules produced a trajectory that remained in the region of the two experimental structures. This dramatic solvation effect is apparently the result of the breaking of an interring hydrogen bond between the O2 hydroxyl groups of neocarrabiose as both groups hydrogen bond to solvent. © 1996 John Wiley & Sons, Inc.
