Alkynyl Stearic Acid

Alkynyl stearic acid is can be used to identify and characterize the post-translational acylation of proteins using the powerful click chemistry, a simple and robust two-step labeling and detection technique. Due to the very small size of the alkyne group and its complete absence in any natural molecules the presence of alkynyl group does not affect the biodistribution of alkynyl palmitic acid in comparison to the natural palmitic acid making it a suitable substrate for enzymes.
