초록

게 껍질에서 얻어진 키토산에 아질산나트륨을 가한 후 수산화붕소산 나트륨으로 환원시켜 중합도 2∼3인 2,5-anhydro-D-mannitol의 말단기를 갖는 키토산 올리고당을 합성하였다 염화팔미틴산을 DUP 촉매하에서 키토산 올리고당과 반응시켜 키토산 올리고당에 세 개의 아실기가 결합된 키토산 올리고당 유도체를 얻었으며, 이를 다시 수산화칼륨으로 가수분해하여 N-팔미토일 키토산 올리고당을 합성하였다. 최종적으로 수용액에 분산시킨 후 초음파를 가한 후 형성된 베지클을 TEM 을 이용하여 확인할 수 있었다.

Chitosan oligosaccharide with an average degree of polymerization 2-3 was prepared by degradation reaction using sodium nitrite, and the resulting aldehyde group was reduced to hydroxy group. N-palmitoyl, O-palmitoyl chitosan oligosaccha was obtained from the reaction between palmitoyl chloride and oligosaccharide under DMAP catalyst. Alkaline hydrolysis was carried out to remove the O-palmitoyl group. After dispersion and ultrasonication in aqueous solution, N-palmitoyl chitosan oligosaccharide gives vesicle structure. Its structure and size was analyzed by TEM.
