N-Glycinated lyso-ceramide trihexoside is an analogue of the important biomolecule lyso-ceramide trihexoside (globotriaosylsphingosine, lyso-Gb3). It is ideal for use as an internal standard in the extraction and mass spectrometry (MS) analysis of lyso-ceramide trihexoside.(1) The free amine group gives this product very similar physical characteristics to the natural lyso-ceramide trihexoside while the glycine adds an additional 57 units to the molecule making it easy to detect by MS. lyso-Ceramide trihexoside and the acylated ceramide trihexoside (globotriaosylceramide, Gb3) are important biomarkers for the lysosomal storage disorder Fabry disease.(2) Fabry disease is characterized by a deficiency in the enzyme - galactosidase, resulting in an accumulation of ceramide trihexoside and lyso-ceramide trihexoside.(3) Early detection and treatment of this disease is critical to prevent damage to various organs.
