This paper deals with the release and transport of lipids in the prawn, Penaeus japonicus. The hepatopancreas obtained from the prawn after injection of palmitic acid-14C contained an abundance of radioactive phospholipids (PL) with rather large amounts of triglycerides (TG) and free fatty acids (FFA). When the in vivo prelabelled hepatopancrtas, containing mainly radioactive PL and TG, was reincubated in vitro in the prawn serum, PL, TG, and FFA were released into the incubation medium. Also, the in vitro reincubation of the predlabelled hepatopancreas containing mainly TG showed that TG was the major liped class released into the incubation medium. In addition, the present study suggests that the release of hepatopancreatic lipids in the prawn is accelerated by some factor (probably lipoproteins) of the prawn serum. These facts can be explained by the proposal that PL, TG, and FFA are the principal lipid moieties released from the hepatopancreas into the hemolymph in the prawn, P. japonicus.
