멍게 껍질로부터 분리정제한 적색 Carotenoprotein의 특성 2. Carotenoid의 화학구조

Purification and Characterization of the Red Carotenoprotein from the Skin of Ascidian, Halocynthia roretzi 2. Chemical Structure of Carotenoid

Carotenoids liberated from the red carotenoprotein from the skin of ascidian(Halocynthia roretzi)were developed on TLC, and two bands were obtained with different Rfvalues. Their chemical reactivities and spectroscopic properties were studied and elucidated as astaxanthin diester and astaxanthin monoester. After saponification of carotenoid ester, GC analysis was performed. The carotenoid ester contained oleic acid, palmitic acid and palmitoleic acids as 50% of total amount, and had higher content unsaturated fatty acid including eicosapentanoic acid than saturated fatty acid.
