概要

• 論文の詳細を見る

• The chemical and stereochemical structure of lenthionine has been established by the X-ray method. Lenthionine crystallizes in the monoclinic system, space group P2_1/a-C^5_<2h>, with four molecules of S_5 (CH_2)_2 in the unit cell. Using a three-dimensional Patterson function and minimum functions, all atomic positions were determined. The least squares method was adopted to distinguish CH_2 groups from sulfur by the temperature factors. Thus the three-dimensional molecular geometry has been elucidated to be in a chair form, having C_2 pseudo-symmetry.
