운반체를 함침시킨 액막에 의한 아미노산의 이동
Transport of Amino Acids through the Immobilized Liquid Membrane Containing Carrier
초록
운반체로 Aliquat 336을 다공성 고체지지막에 함침시킨 액막을 이용하여 아미노산과 첨가전해질의 역방향이동계에서 아미노산의 이동속도에 대한 모델을 세워 분석하였다. 정상상태의 아미노산의 이동속도 및 농도분포를 Nernst-Planck식을 이용하여 유도하였고 이동속도에 영향을 주는 확산전위계수（osmo-electric coefficient）를 정의하였다. 실험결과 막전위가 커질수록 아미노산의 이동속도는 감소하였고 이론식에서 정의된 확산전위계수는 아미노산의 flux와 선형적 관계를 나타내었다. 첨가전해질의 종류에 따른 아미노산의 이동속도는 수화에너지의 크기와 반대경향을 나타내었고 아미노산도 같은 경향으로 Try>Tyr>Hip의 순서로 감소하였다.
The transport of amino acids through the immobilized liquid membrane containing Aliquat 336 as a carrier was analyzed by a theoretical model. The flux and concentration distribution of amino acids at steady-state were derived with Nernst-Planck equation in counter-transport system of amino scids and added electrolytes, and the osmo-electric coefficient which affect the flux to a large extent was defined.
It was concluded theat the flux of amino acids decreased with increasing membrane potentials and was linear with the osmo-electric coefficient. The transport rate of amino acids had the inverse relation with the magnitude of hydration energy. Also the transport rate according to the amino acids increased in the order : tryptophan>tyrosine>hippuric acid.
