Perivitellin-2
Perivitellin-2 (PV2) is a pore-forming toxin present in the egg perivitelline fluid of the apple snails ''Pomacea maculata'' (PmPV2) and ''Pomacea canaliculata'' (PcPV2). This protein, called Perivitellins, perivitellin, is massively accumulated in the eggs (~20 % total protein). As a toxin PV2 protects eggs from predators, but it also nourishes the developing snail embryos. Structure and stability These ~172-kDa proteins are dimers of AB toxins, each composed of a carbohydrate-binding protein of the tachylectin family (targeting module) disulfide-linked to a Pore-forming toxin, pore-forming protein of the Membrane Attack Complex and Perforin (MACPF) family (toxic unit). Like most other studied perivitellins from ''Pomacea'' snails, PV2s are highly stable in a wide range of pH values and withstand gastrointestinal digestion, characteristics associated with an antinutritive defense system that deters predation by lowering the nutritional value of the eggs.

Private (rank)
A private is a soldier, usually with the lowest Military rank, rank in many armies. Soldiers with the rank of private may be conscription, conscripts or they may be professional (career) soldiers. The term derives from the term "private soldier". "Private" comes from the Latin word ''privus'' or perhaps ''privo'' that meant an individual person and later an individual without an Official (other), office. Asia Indonesia In Indonesia, this rank is referred to as ''Tamtama'' (specifically ''Prajurit'' which means soldier), which is the lowest rank in the Indonesian National Armed Forces. In the Indonesian Army, Indonesian Marine Corps, and Indonesian Air Force, "Private" has three levels, which are: Private (''Prajurit Dua''), Private First Class (''Prajurit Satu''), and Chief Private (''Prajurit Kepala''). After this rank, the next promotion is to Corporal. File:prada pdh ad.png, Private (''Prajurit Dua'') File:pratu pdh ad.png, Private First Class (''Prajurit Satu'') ...
