The reaction of N-acylpyroglutamic acid with ammonia proceeds in two pathways. The one results in N-acylglutamine as a product, and the other in pyroglutamic acid and an amide formed from the N-acyl group. The ratio of the yields of the two reactions changes with the N-acyl group, being correlated with the acidity of the carboxylic acid from which the N-acyl group is derived, and also with the steric
N-酰基焦谷氨酸与氨的反应以两种途径进行。一个产生 N-酰基谷氨酰胺作为产物,另一个产生焦谷氨酸和由 N-酰基形成的酰胺。两个反应的产率之比随 N-酰基而变化,这与衍生 N-酰基的羧酸的酸度以及基团的位阻有关。
