deglycosylation
Stripping carbohydrate chains
Deglycosylation is the biochemical process of removing sugar molecules (glycans) from proteins or other molecules to which they are attached.
This is the reverse of glycosylation, where sugars are added.
Scientists use deglycosylation in research to study how sugar attachments affect protein function, stability, or immune recognition.
Enzymatic deglycosylation revealed the protein's true molecular weight.
