[Phospholipids and cholesterol in oocytes and embryos of the loach (Misgurnus fossilis)].

The qualitative composition of lipid fractions in loach oocytes and embryos at different developmental stages is investigated by TLCh on silica gel. The variability in density of minor phospholipid fractions (lyzophosphatidyl choline, phosphatidylglycerine and cholesterol) is established in the period of synchronous divisions of blastomeres. The constant composition of major fraction of phospholipids in early embryogenesis of loach is registered.
