칠성무당벌레의 유충, 용, 성충에서 인지질의 조성을 TLC를 이용하여 조사하였다. 초령 유충에서는 lysophatidylethanolamine (Lyso-PE), phosphatidylethanolamine(PE), phosphatidylglycerophosphate (PGP)및 sphingomyelin (SPH)등 4가지 인지질 만이 확인되었으나, 2령 유충에서는 이외에도 phosphatidylinositol (PI)이 검출되었고, Lyso-PE 대신 phosphatidylcholine (PC)이 검출되었다. 또한 PI, PC 및 PE는 전용, 용 및 성충기 동안에 모두 확인되었다. PGP와 SPH spot는 암, 수에서 모두 노화에 따라 감소하였으며, SPH spot는 수컷에서 보다 더 크게 나타났다.
The phosphatides from the larvae, pupae and adults of Coccinella septempunctata were evaluated through TLC. The first instar larva possesses only four phosphatides, which include lysophosphatidylethanolamine (Lyso-PE), phosphatidylethanolamine (PE), phsphatidylglycerophosphate (PGP), and sphingomyelin (SPH). The second instar larva in addition to the above phospholipids, also possesses phosphatidylinositol (PI), and lyso-PE is replated by phosphatidylcholine (PC). The phospholipids including PI, PC and PE are represented throughout the prepupal, pupal and adult life of this beetle. PGP and SPH spot diminished with aging in both the sexes. PE spot developed into larger area in the female as compared to the male of this insect.
