GLYCOLIPID PATTERNS DURING XENOPUS EMBRYO DEVELOPMENT

Glycolipid patterns have been studied during the first six days of Xen opus embryo development. Glycolipid contents showed a sharp increase m ore evident after the third day of development. Glucosylceramide and s ulphatide are not only the most represented species, but also those wh ich exhibit a statistically significant percentage change during early development. Among gangliosides, GD3 is the most represented specie. Two polysialylated gangliosides with not yet established structures ar e also present.
