Glycoprotein
Glycoprotein — A protein with one or more covalently attached carbohydrate chains, with glycosylation affecting peptide receptor binding, stability, and immune recognition.
What Is a Glycoprotein?
A glycoprotein is a protein with covalently attached sugar chains (glycans). Most cell-surface receptors and secreted proteins are glycoproteins. Glycosylation affects peptide folding, stability, immunogenicity, and pharmacokinetics. Glycopeptide synthesis combines peptide chemistry with carbohydrate chemistry.
Context
- Glycopeptide drugs: Vancomycin, teicoplanin are glycopeptide antibiotics
- Glyco-engineering: Site-specific glycosylation to tune PK and immunogenicity
- Synthesis: Pre-formed glyco-amino acid building blocks for on-resin incorporation
