The molecule is a glycoside that is alpha-L-fucose in which the hydrogen of the anomeric hydroxy group is replaced by a 4-aminobutyl group. A synthetic version of the alpha-fucosyl glycoside (AFG) epitope from the major peanut allergen glycoprotein Arachis hypogaea h2 (Ara-h2). It has a role as an allergen. It derives from an alpha-L-fucose.
