Recent findings in other Pomacea species showed that the polysaccharide galactogen, the most abundant embryo nutrient, is also nondigestible, adding another defense that at the same time also prevents egg desiccation (Giglio et al., 2016).
High levels of estrogens, progesterone and placental galactogen result in decreased glucose tolerance during normal pregnancies.
Starvation also caused a reduction in the synthesis of galactogen and glycogen in the albumen gland and the mantle of thepond snail Lymnaea stagnalis, [23].

Among the environmental factors that may influence the metabolism of snails, some authors have shown that the photoperiod exerts influence on sexual maturation, egg laying and carbohydrates metabolism, specially glycogen and galactogen (Wijsman, 1989; Dogterom et al., 1983; 1985).
Early studies identified carbohydrates such as galactogen and proteins as two major categories of nutrition in CF, which together make up more than 94% of its dry weight in the freshwater pond snail Lymnaea stagnalis (Horstmann, 1956; Morrill et al., 1964; Wijsman and van Wijck-Batenburg, 1987).
