数種魚類アクトミオシンの表面疎水性とアスタキサンチン,カンタキサンチンとの結合の関連性

抄録

Actomyosins from coho salmon, rainbow trout, stone flounder, carp, skipjack, common mackerel and jack mackerel white muscles, and coho salmon dark muscle were combined with astaxanthin or canthaxanthin. These actomyosins bound with a high affinity to astaxanthin. The actomyosins from salmonids showed a higher affinity to ketocarotenoids than those of other fishes except common mackerel. A correlation between surface hydrophobicity of actomyosins and combination of astaxanthin and/or canthaxanthin with actomyosins was observed. The selective accumulation mechanism for ketocarotenoids is discussed.
