The molecule is a glycophytoceramide that consists of phytosphingosine having a 6-acetamido-6-deoxy-alpha-D-galactosyl attached at the O-1 position via a glycosidic linkage and a (Z)-tetracos-15-enoyl group attached to the nitrogen. It has a role as a ceramide allergen. It derives from an alpha-D-galactose.
(Z)-N-[(2S,3S,4R)-1-[(2S,3R,4S,5R,6R)-6-(acetamidomethyl)-3,4,5-trihydroxyoxan-2-yl]oxy-3,4-dihydroxyoctadecan-2-yl]tetracos-15-enamide
