Palmitic Acid Alkyne (Synonyms: Alk-14)

Protein S-palmitoylation is the post-translational acylation of proteins and serves to regulate localization, stability, and interaction with associates and substrates.[1] Palmitic acid alkyne is a form of palmitic acid with an ω-terminal alkyne. The terminal alkyne group can be used in linking reactions, known as click chemistry; this chemistry is characterized by high dependability and specificity of the azide-alkyne bioconjugation reactions. [2] [3]The use of palmitic acid alkyne and related lipids in isolating palmitoylated proteins has been described. [4] [5] [6]
