Ancylostoma ceylanicum and Nippostrongylus brasiliensis decarboxylated most of the amino acids examined, but only a few at significant rates. The former nematode in general possessed higher activities. Striking differences between the two parasites were, however, noticed regarding the metabolism of some of the amino acids. For instance, while alanine followed by aspartate produced highest amounts of 14CO2 in the presence of A. ceylanicum, proline exhibited maximum decarboxylation in case of N. brasiliensis. Tyrosine and lysine, on the other hand, did not liberate detectable CO2 with either parasite. Likewise, although large number of amino acids underwent transamination with 2-oxoglutarate, only some of them elicited appreciable activity for any of the two parasites.
锡兰钩口线虫和巴西日圆线虫能使所检测的大多数氨基酸脱羧，但只有少数几种氨基酸的脱羧速率显著。一般来说，前一种线虫具有更高的活性。然而，在某些氨基酸的代谢方面，这两种寄生虫之间存在显著差异。例如，在有锡兰钩口线虫存在的情况下，丙氨酸其次是天冬氨酸产生的14CO2量最高，而在巴西日圆线虫的情况下，脯氨酸表现出最大的脱羧作用。另一方面，酪氨酸和赖氨酸与这两种寄生虫中的任何一种都不会释放出可检测到的CO2。同样，虽然大量氨基酸与2-氧代戊二酸发生转氨作用，但其中只有一些对这两种寄生虫中的任何一种都产生了可观的活性。
