An object of the present invention is to provide glycoamino acid as an amino acid precursor with improved properties (particularly water-solubility, stability in water, bitter taste etc.). The present invention relates to a compound represented by the formula (I): wherein each symbol is as defined in the DESCRIPTION, or a salt thereof.

Glycoamino acid and use thereof

Compounds represented by formula (I): wherein each symbol is as defined herein, have an immunostimulatory effect and are useful as immunostimulating agents, particularly as adjuvants, and for compositions containing such a compound, and for vaccines containing such a compound and an antigen.

Immunostimulating agent

Compounds of formula (I&#x2033;) wherein:

Glycoside compound

Capsinoids of formula (3) may be conveniently prepared in a high yield, in a short time, without using a dehydrating agent by esterification of a fatty acid of formula (1) with a hydroxymethylphenol of formula (2) using an enzyme without a solvent or in a low-polar solvent. Addition of a fatty acid represented by formula (4) is effective for stabilizing the ester compound of formula (3). wherein each symbol is as defined in the specification.

Production method of capsinoid by dehydrating condensation, stabilizing method of capsinoid, and capsinoid composition
