title: Effect of maternal diet on the distribution of phospholipids and their fatty acid composition in Xenopus laevis embryos.
abstract: We determined the total phospholipid content, the percentage distribution of different phospholipid classes and their fatty acid composition in 6-day-old embryos obtained from Xenopus laevis females fed on two different diets. A first group of females was fed on beef liver, and a second one was nourished with commercial fish food very rich in omega-3 fatty acids. The embryos showed different patterns of phospholipids that had dissimilar fatty acid compositions. Phosphatidylinositol content was particularly affected. Due to the functional roles of this phospholipid as part of the transmembrane signaling machinery, it is possible to hypothesize that maternal diet might influence cell metabolism in amphibian embryos.
