WebAug 13, 2024 · An organometallic compound is one which has metal-carbon bonds, and between one and eight carbon atoms in a hydrocarbon ligand bond to a metal. Hapticity describes the number of atoms in a ligand that have direct coordinative interaction with the metal and the number is added to η. An example is η 5 (pentahapto)-cyclopentadienyl … WebLigands bind to receptors, which cause conformational changes and various effects on the cell. Integral membrane proteins span the lipid bilayer. These proteins commonly act as receptors and bind to ligands to produce conformation changes. They cannot leave the lipid bilayer, and thus are never ligands that can bind to other receptors.
