초록
구조와 용해도가 다른 4종류의 다당류(옥수수전분, 쌀전분, 고구마전분 및 셀룰로오스) 내의 1차 alcohol기를 특이적으로 산화시켜 제조된 polyglucuronic acid를 polyglucuronic acid C5-epimerase와 반응시켜 algin 유사 물질을 값싸게 대량으로 구득하고자 하였는 바, 신선한 소의 간을 마쇄한 후
We could produce algin-like biomaterial of polyiduronan using polyglucuronic acid C5-epimerase with polyglucuronic acid prepared by specific oxidation of primary alcohol groups of four kinds of polysaccharides(corn starch, rice starch, sweet potato starch, and cellulose). The enzyme activity was determined by the modified Dische carbazole methodology with the isolated crude enzyme from the supernatant centrifuged at
