초록
우렁쉥이의 육에 존재하는 carotenoprotein을 추출하여 이온교환수지 및 겔크로마토그래피를 이용하여 정제하였으며, 정제된 carotenoprotein의 분자량, pH 안정성, 열안정성, 변성제의 영향, 아미노산 조성 및 지방산 조성을 분석하였다. Carotenoprotein의 정제도는 5배, 수율은 2.9%였으며, 1 mg당
A carotenoprotein from the muscle of Ascidian (Halocynthia roretzi) was purified by ion exchange chromatography and gel filtration chromatography, and analyzed molecular weight, stability of pH and heat, effect of denaturing agents, amino acids and fatty acids composition. The purified carotenoprotein had absorption maxima of 463 nm and 439 nm. The carotenoprotein had an approxmimate molecular weight of 64.4 kDa in polyacrylamide gel electrophoresis. The amino acid compositions of carotenoprotein were mainly Gly (15.39%), Asn (11.31%), Gln (10.62%) and Ser (13.35%). The major fatty acids composition of carotenoprotein were
