D-Thiazolidine-4-carboxylic acid is a good substrate for hog kidney D-aminoacid oxidase. Data are presented showing that the only oxidation product is delta 3-thiazoline-4-carboxylic acid, which does not undergo further spontaneous degradation. Thus, the oxidation of D-thiazolidine-4-carboxylic acid by D-aminoacid oxidase differs considerably from the oxidation of its L-isomer catalyzed by rat liver mitochondria which gives as final product N-formylcystine, possibly through the intermediate delta 2-thiazoline-4-carboxylic acid.
D-噻唑烷-4-羧酸是猪肾D-氨基酸氧化酶的良好底物。所呈现的数据表明，唯一的氧化产物是δ3-噻唑啉-4-羧酸，它不会进一步自发降解。因此，D-氨基酸氧化酶催化D-噻唑烷-4-羧酸的氧化与大鼠肝线粒体催化其L-异构体的氧化有很大不同，后者最终产物是N-甲酰胱氨酸，可能是通过中间体δ2-噻唑啉-4-羧酸形成的。
