…The central carbon atom of the trihydroxyglutaric acid isomer (formula c) appears to be an asymmetric carbon atom (H, OH, and two CH(OH)COOH groups with different configurations), but the molecule has a symmetric plane, making it optically inactive. This phenomenon is called pseudo-asymmetric, and this type of asymmetric carbon atom is called a pseudo-asymmetric carbon atom. Optical isomerism [Takeuchi Takato]. … *Some of the terminology explanations that mention "pseudoasymmetric carbon atom" are listed below.

…トリヒドロキシグルタル酸の異性体(式c)の中央の炭素原子は一見不斉炭素原子(H,OH,立体配置の異なる二つのCH(OH)COOH基)のように見えるが,分子に対称面があるため光学不活性となる。この現象を擬不斉,この種の不斉炭素原子を擬不斉炭素原子という。光学異性【竹内 敬人】。… ※「擬不斉炭素原子」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
