Lysophosphatidylcholine from white muscle of bonito Euthynnus pelamis (Linnaeus): involvement of phospholipase A1 activity for its production.
A fairly large amount of lysophosphatidylcholine (LPC) was detected in the fresh muscle of bonito Euthynnus pelamis (Linnaeus). The major fatty acid esterified in LPC were highly unsaturated fatty acids, such as docosahexaenoic and eicosapentaenoic acids, and the form was mainly composed of 1-lyso-2-acyl-sn-glycero-3-phosphocholine (1-LPC). The content of this species continued to increase during 4 months of frozen storage and then decreased. Phospholipase A1 activity detected in the bonito muscle was supposed to be responsible for the accumulation of LPC.
