Abstract:
It is an object of the present invention to provide a method for producing an 11-sugar sialylglycopeptide easily and with good yield and a high degree of purity on an industrial scale from defatted bird egg yolks. The present invention provides a production method of an 11-sugar sialylglycopeptide. More specifically, the present invention provides a production method of an 11-sugar sialylglycopeptide comprising: an extraction step of extracting defatted bird egg yolks with water or a salt solution to obtain a liquid extract of a glycopeptide, a precipitation step of adding the liquid extract to a water-soluble organic solvent to precipitate the glycopeptide, and a desalting step of desalting the precipitate.
