TAG는 식물에서 생산하고 자연에서 얻을 수 있는 많은 에너지를 소유하고 풍부한 탄화수소입니다. 화학적으로 기존디젤 구조와 유사하여 사용하기 쉽습니다. 그러나, 식물성오일 TAG는 지방산으로부터 에스터반응을 통해 글리세롤과 지방산메틸에스테르로 분리합니다. 이때 분리된 지방산메틸에스테르가 바이오디젤로 사용됩니다. 바이오디젤은 기존 디젤에 비해 많은 장점을 가지고 있습니다. 하지만 단점또한 가지고 있는데 바로 바이오 디젤을 만들기 위한 연료의 원료가 부족하다는 점입니다. 그래서 바이오 디젤이 확산되기 위해서는 식물성오일의 생산량을 증가시켜야합니다. 이런한 단점을 극복하기 위하여 저는 오일함량을 증가시키는 방안을 종합하여 정리하였습니다. 먼저 식물에서 지방산을 합성하는 과정과 합성된 지방산을 가지고 TAG을 합성하는 방법을 이해가 필요합니다. 그리고 최근에는 식물의 종자가 아닌 다른 영양조직에서도 오일함량을 증가시키는 방안이 연구되어지고 있습니다. 저는 LEC2 효소를 이용한 증가방안을 정리하였습니다. 이러한 여러방안을 종합하여 TAG생합성 및 조절에 관여하는 유전자들의 과다발현체 또는 억제방법을 통해 보다 많은 바이오디젤생성에 기여할 수 있는 가능성을 확인하였습니다.

TAG는 무엇일까
Figure1(TAG의 Structure)
에너지 독립에 대한 필요성 증가와 이산화탄소 수준의 증가에 대한 우려의 증가는 우리의 현재 화석 연료 소비를 줄일 수 있는 재생 가능 연료에 대한 탐색을 증가했다. 그러한 연료 중 하나는 식물성 기름에서 추출한 지방산의 메틸에스테르로 구성된 바이오디젤이다. 동물성 지방을 포함한 다른 것도 가능하다. 식물유는 주로 TAG이 구성분자이고 에스테르화 된 3개의 지방산사슬로 구성되어있다. 지방아실체인은 가솔린과 디젤에서 발견되는 분자의 대부분을 구성하는 지방족 탄화수소와 화학적으로 유사하다. 가솔린의 탄화수소는 5~12개의의 탄소 원자를 가지고 있으며, 그리고 휘발성의 연료는 공기와 혼합하여 불을 붙여 기존 엔진에서 점화한다.
