Alkyne metathesis is extensively used in ring-closing operations and RCAM stands for ring closing alkyne metathesis.

Alkyne protons by contrast resonate at high field in a 2 – 3 ppm range.

Path e to 6: Alkyne hydrolysis with NaAuCl < sub > 4 </ sub > in MeOH.

Alkyne reduction is stereoselective, occurring via syn addition to give the cis-alkene.

Clathrin heavy chain is, in concept, broken down into multiple subdomains, starting with the N-terminal domain, followed by the ankle, distal leg, knee, proximal leg, and trimerization domains.

The light chains bind primarily to the proximal leg portion of the heavy chain with some interaction near the trimerization domain.

Often, trimerization competes with polymerization.

It signals through trimerization of FasR, which spans the membrane of the " target " cell.

This trimerization usually leads to apoptosis, or cell death.

Membrane-anchored Fas ligand trimer on the surface of an adjacent cell causes trimerization of Fas receptor.

Soluble FasL is less active than its membrane-bound counterpart and does not induce receptor trimerization and DISC formation.
