0 a chemical bond in which two atoms share one or more pairs of electrons that hold them together
1 a chemical bond in which two atoms share one or more pairs of electrons, which hold them together
This structure is unique in enzymes in that the two ends are the only form of covalent bond attachment to rest of the protein.
Thereafter, b-ionone freely exchanged within the binding pocket during perfusion because the truncated retinoid cannot form a covalent bond with opsin.
The mechanism of the attractive force in a covalent bond relies on highly complex electromagnetic interactions between electrons with magnetic spin components.
This is of course equivalent to saying that as a covalent bond begins to form between the phosphorus and the 2h-oxygen, the burden of the negative charge becomes relieved.
This type of chemical bond is either a non-polar covalent bond or a polar covalent bond.
As such, the chemical linkage (usually a covalent bond) should be subjectable to biodegradation, such as hydrolysis, by an enzymatic or non-enzymatic mechanism.
What makes the isopeptag different from other peptide tags is that it can bind its binding protein through a permanent and irreversible covalent bond.
If the unpaired electrons can spin-pair to form a covalent bond, then the covalent bonding interaction can lower the energy of the charge transfer state.
