一些活动被肾脏酶在相应二酯形成单酯的过程中注意到;只观察到非常微弱的单酯裂解活性。与从对苯二甲酸二丁酯形成对苯二甲酸的速率相比,肾脏酶从对苯二甲酸二丁酯形成间苯二甲酸的速率高出两倍多。在所有制备物中,半酯形成速率相对较快。酸形成缓慢。这表明酸形成是限速步骤。
Some activity was noted by renal enzymes in the formation of monoester from the correspondlng diesters; only very weak activity for the cleavage of the monoesters was seen. Compared with the formation rate of terephthalic-acid from di-n-butyl-terephthalate, the rate of isophthalic-acid formation from di-n-butyl-isophthalate was more than twice as high with renal enzymes. Half ester formation rate was relatively rapid in all preparations. Acid formation was slow. This suggested that acid formation was the rate limiting step.
