About: Galactogen

An Entity of Type: chemical substance, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org:8891

Galactogen is a polysaccharide of galactose that functions as energy storage in pulmonate snails and some Caenogastropoda. This polysaccharide is exclusive of the reproduction and is only found in the albumen gland from the female snail reproductive system and in the perivitelline fluid of eggs. Galactogen serves as an energy reserve for developing embryos and hatchlings, which is later replaced by glycogen in juveniles and adults. The advantage of accumulating galactogen instead of glycogen in eggs remains unclear, although some hypotheses have been proposed (see below).

  • Galactogen is a polysaccharide of galactose that functions as energy storage in pulmonate snails and some Caenogastropoda. This polysaccharide is exclusive of the reproduction and is only found in the albumen gland from the female snail reproductive system and in the perivitelline fluid of eggs. Galactogen serves as an energy reserve for developing embryos and hatchlings, which is later replaced by glycogen in juveniles and adults. The advantage of accumulating galactogen instead of glycogen in eggs remains unclear, although some hypotheses have been proposed (see below). (en)
  • El galactógeno es un polisacárido de galactosa que sirve para el almacenamiento de energía en los caracoles pulmonados y algunos Caenogastropoda.​ Este polisacárido es exclusivo de la reproducción, y solo se encuentra en la del sistema reproductor femenino de estos caracoles y en el fluido perivitelino de los huevos. El galactógeno sirve como reserva de energía tanto para los embriones en desarrollo como para los juveniles recién eclosionados, y es luego reemplazado por el glucógeno en juveniles de estadios avanzados y en adultos.​ Aún no se ha identificado la ventaja de acumular galactógeno en vez de glucógeno en los huevos de caracoles, pero se han propuesto algunas hipótesis al respecto (ve abajo).​ (es)
