[Lipovitellins in Palaemon adspersus (Rathke, 1837)].

The study of the ovarian cycle of Palaemon adspersus shows the occurrence of two lipo-glycoproteins accumulated into the ovocytes during vitellogenesis. The molecular weight of the main protein constituent in vitellus is evaluated to about 350 000 daltons. This protein is formed by two subunits having a similar molecular weight. The incorporation in vitro of [14C] leucine shows the participation of the ovary to lipovitellin synthesis.
