Palmitoleic acid alkyne, an ω-terminal alkyne derivative of palmitoleic acid, facilitates click chemistry applications. This compound has played a crucial role in examining protein palmitoylation processes. Specifically, the cis form of palmitoleic acid alkyne selectively tags wild-type Wnt3a protein within mouse fibroblast L-cells expressing Wnt3a and its secretion in conditioned media, distinguishing itself from the trans form and proving ineffective against the S209A mutant Wnt3a.
Docosahexaenoic acid alkyne, an ω-alkyne derivative of docosahexaenoic acid, enables Cu(I)-catalyzed cycloaddition with azide-containing molecules for efficient click chemistry applications. It can be further utilized to produce alkyne-modified products like glycerophospholipids. Additionally, this compound permits the monitoring of fatty acid metabolism in cells through click chemistry linkage to fluorophores.
