Glycobiology × machine learning

Glycan data you can act on.

SweetSense Analytics gives biotech and pharma teams direct access to the methods behind glycowork, CandyCrunch and LectinOracle, applied by the scientist who built them.

From raw spectra to a decision

Six areas where glycoscience questions stall most teams, and where our methods move them forward.

Ser/Thr β3 α3 β4 β6
sialyl core 2 O-glycan

Glycomics statistics

Differential abundance, motif enrichment and time-series analysis for N- and O-glycomics, built on compositional data analysis so results hold up to scrutiny.

β3 α2 α4
Lewis b

Structures from MS/MS

Deep-learning annotation of tandem mass spectra into full glycan structures with CandyCrunch, including diagnostic ion analysis for difficult isomers.

β4 α3 α3
sialyl Lewis X

Binding and specificity

Predict and interpret how lectins, antibodies and microbial adhesins recognize glycans, from array data to target-level specificity maps.

β4 β4 α3 α3 α6 α6
Man5 N-glycan

Biosynthetic modeling

Trace a glycome shift back to the enzymes and pathways that drive it, to guide cell line engineering or explain a disease phenotype.

β4 α2 α3
blood group A, type 2

3D structure at scale

Glycan conformations and protein-glycan contacts analyzed across thousands of structures with GlyContact, for glycoprotein design and epitope work.

LNFP I, a milk oligosaccharide

Custom models and data

Machine learning models, curated datasets and pipelines built for your glycan or glycoprotein question, delivered as code your team owns.

Engagements

Ways to work together

Hourly

Expert consultation

Focused sessions on a specific question: data review, method choice or a second opinion before a decision.

For start-ups

Scientific advisory

A standing monthly arrangement for companies that need regular glycoscience input. Equity can form part of it.

Fixed scope

Defined projects

An agreed analysis with clear deliverables: a report, publication-quality figures and reproducible code.

Open methods

Built on tools the field uses

The software behind our work is open source and used by glycobiology labs and companies worldwide. You get the people who wrote it.

  • glycoworkThe Python toolkit for glycan data science: parsing, statistics, motifs, networks and GlycoDraw figures like the ones on this page.
  • CandyCrunchDeep learning that predicts glycan structures directly from LC-MS/MS data.
  • GlyContactGlycan 3D structure and protein contact analysis at scale.
  • LectinOracleDeep learning model for protein-glycan binding prediction.
