Vegetable oils (triacylglycerols) produced mainly in seeds of plants are used for valuable foods that supply essential fatty acids for humans as well as industrial raw materials and biofuel production. As the demanding for vegetable oils has increased, plant metabolic engineering to produce triacylg...

식물 종자의 지방이 활용되는 곳은? | 식물 종자의 지방은 인류에게 불포화 지방산을 공급하는 필수 식품(Huffman et al. 2011)인 동시에 자동차 연료인 바이오 디젤과 세제, 윤활유, 제약원료 등 다양한 생필품의 원료이다(Cahoon et al. 2007). | |
잎은 어떤 조직인가? | 잎은 엽록체에서 광합성을 통해 대기중의 이산화탄소를 고정하여 저장조직(sink)인 종자 등에 탄소를 공급(source)하는 조직이다. 낮에 광합성에 의해 고정된 탄소는 대부분 자당(sucrose) 형태로 다른 조직으로 이동하거나 전분(starch) 형태로 잎의 엽록체 안에 저장되며 밤 동안 전분은 자당으로 분해되어 식물생장에 필요한 에너지로 사용된다(Weise et al. | |
잎의 주요 탄수화물을 지방으로 전환할 때의 장점은? | 잎의 주요 탄수화물을 지방으로 전환한다면 세가지 장점이 있다. 첫째, 지방은 탄수화물보다 단위 질량당 에너지 효율이 높다. 둘째, 지방은 식물조직에서 탄수화물보다 작은 부피를 차지하기 때문에 많은 에너지 저장이 가능하다. 셋째는 지방은 추출·정제 과정이 탄수화물보다 간단하여 바이오 연료 및 산업원료로 사용이 용이하다. |
