Abstract

The molecular structure of 6-L-alanineferrirubin tetradecahydrate, [Fe(C41H64N9O16)].14H2O, has been determined in order to confirm its chemical structure. The structural results show that the presence of an alanine in place of a serine or a glycine at position 6 in the cyclic hexapeptide has very little effect on the conformation of the 18-membered ring or on the geometry of the octahedral iron coordination.

摘要

为了确认其化学结构，已测定了6-L-丙氨酸铁红素十四水合物[Fe(C41H64N9O16)].14H2O的分子结构。结构结果表明，在环状六肽的6位上，用丙氨酸取代丝氨酸或甘氨酸，对18元环的构象或八面体铁配位的几何结构影响很小。
