Abstract
To determine the metabolism of leucine during the cuticle formation and the sclerotization process in Pieris rapae L., $U-^3$H-leucine or $U-^4$C-tyrosine is injected into the haemolymph of newly molted pupa through dorsal cuticle of heart area. The results show that leucine as a common amino acid participates in the synthesis of cuticle protein over the first 3 hr after ecdysis. It is also shown that leucine in the haemolymph at ecdysis is freely being moved between major internal organs during the short time period post-ecdysis, providing the evidence for some involvements including haemolymph protein synthesis and storage of fat body and gut in metabolism of leucine.
배추흰나비(Pieris rapae L.)의 용시기 (pupal stage)의 큐티를 형성 및 경화에 따른 leucine의 대사를 규명하기 위하여 $^3H-leucine$ 또는 $^14C-tyrosine$을 용화직후 혈림프에 주입시켰다. 혈림프내의 leucine은 탈피후 3시간 동안에 걸쳐 큐티를 단백질 합성에 관여하였고 또한 혈림프, 지방체, 장 및 큐티클 사이를 자유로이 이동하였는데 이것은 leucine대사에서 지방체 및 장이 혈단백질의 합성 및 저장에 관여하고 있다는 자료를 암시하여 준다.
