Aldehyde
Aldehyde — An organic compound containing a formyl group, used as a reactive handle in peptide conjugation and bioconjugate chemistry.
What Is an Aldehyde?
An aldehyde (-CHO) is a reactive carbonyl functional group used in peptide chemistry for site-specific conjugation and cyclization reactions. Aldehyde groups react selectively with hydrazides, aminooxy groups, and alpha-nucleophiles under mildly acidic conditions (pH 4-6), enabling bio-orthogonal peptide modification.
Applications
- Oxime ligation: Aldehyde + aminooxy → oxime bond. Used for peptide-peptide and peptide-polymer conjugation
- N-terminal Ser/Thr: Periodate oxidation generates N-terminal aldehyde for site-specific conjugation
- Reductive amination: Aldehyde + amine + NaBH3CN → stable secondary amine linkage
