# Monosaccharide structure – Laboratory Analysis

## Your need: analyzing monosaccharide structure

**Monosaccharide composition** analysis is a fundamental step in characterizing glycoproteins, [polysaccharides](https://filab.fr/en/sectors-of-activity/biopharmaceutical/biotherapeutic-recombinant-protein-characterization/polysaccharide-analysis.md), and active ingredients derived from biotechnology.

The nature and proportion of simple sugars (glucose, galactose, mannose, fucose, amino sugars, etc.) determine not only the identity of the molecule but also directly impact its biological activity and stability.

FILAB laboratory supports R&D and Quality departments in the precise determination of the structure and stoichiometric ratio of monosaccharides, ensuring your products comply with international standards.

### Our monosaccharide analysis services

**Identification and quantification**: Precise assay of neutral sugars, amino sugars (GlcNAc, GalNAc), and uronic acids.

**Process development support**: Monitoring the stability of the glycosidic structure during purification stages.

 

**Carbohydrate impurity detection**: Search for contaminants or residual sugars from the manufacturing process.
