title: [Carbohydrates of the chicken egg yolk].
abstract: In the yolk of the eggs of hens receiving traditional feeding hydrocarbon mixtures contained in trace amounts therein were analyzed by a specially elaborated method. For identification and quantification the data of the gas liquid chromatography, chromato-mass-spectrometry and ultraviolet spectrophometry were used. In a complex hydrocarbon mixture chromato-mass-spectrometry helped identify the alkanes of the normal and isoprenoid structure, cycloalkanes, of terpene and sterene types. The alkanes and cycloalkanes fraction content was found to comprise 15-30 per 1 mg of the raw mass of the yolk, of the p-alkanes--1-3 mg, squalene--15-17 mg and of monocyclic arenes--about 1 mg.
