[1] Together with the other perivitellins from Pomacea canaliculata eggs, ovorubin serves a nutrient source for developing embryos, notably to the intermediate and late stages.
[2] Ovorubin contains carbohydrates and carotenoid pigments as main prosthetic groups, [3] which are related to many physiological roles on Pomacea aerial egg-laying strategy.
[3] The carotenoid pigments stabilized by ovorubin also provide the eggs of antioxidant and photoprotective capacities, crucial roles to cope with the harsh conditions of the aerial environment.
[2][4][5][6][7][excessive citations] The presence of carotenoid pigments is also responsible for the brightly reddish coloration of Ovorubin, and therefore snail eggs, which was related to a warning coloration (aposematism) advertising predators about the presence of deterrents.
[10] Like most other studied perivitellins from Pomacea snails, ovorubin is highly stable in a wide range of pH values and withstands gastrointestinal digestion, characteristics associated with an antinutritive defense system that deters predation by lowering the nutritional value of the eggs.
