(Z)- and (E)-2-methyl-butenedioic acids (citraconic and mesaconic acid) were hydrolysed by pig live esterase, PLE. For the diethyl esters the enzyme showed low regioselectivity for both the (Z)- and the (E)-isomers. However, the hydrolysis of dimethyl and dipropyl (Z)-2-methyl-butenedioic acid gave a ratio of the monoesters of 95:5 and 85:15.
(Z)-和(E)-2-甲基-丁烯二酸(柠康酸和中康酸)的二甲酯,二乙酯和二丙酯被猪活酯酶PLE水解。对于二乙酯,该酶对(Z)-和(E)-异构体均显示低的区域选择性。然而,二甲基和二丙基(Z)-2-甲基丁烯二酸的水解给出单酯的比例为95:5和85:15。
