Propionylated
Propionylated refers to a molecule that has been modified by the addition of a propionyl group, derived from propionic acid, to a nucleophilic site such as an amine or hydroxyl group. In organic synthesis, propionylation is a form of acylation that yields propionamide or propionate derivatives, depending on whether the target is an amine or an alcohol. The propionyl group is introduced via reagents such as propionyl chloride, propionic anhydride, or mixed anhydrides, typically in the presence of a base and an appropriate solvent. The result is an amide linkage (R-NH-CO-CH2-CH3) or an ester linkage (R-O-CO-CH2-CH3).
In biochemistry and molecular biology, propionylation also describes a post-translational modification in which a propionyl group
In proteomics and sample preparation, chemical propionylation is used to block free amino groups, particularly the
Safety and handling of propionylating reagents follow standard chemical hygiene practices, as reagents such as propionic
