Negatively charged amino acids have four ionisations zones

1. 1--------pK1 – charge +1

2. pK1---------pKr charge 0

3. pKr---------pK2 charge -1

4. pK2---------14 charge -2

Atomic radii: The atomic radii of an atom depends on its position in the periodic table.

We can never determine the atomic radius of an atom because there is never a zero probability of finding an electron, and thus never a distinct boundary to the atom.

All that we can measure is the distance between two nuclei (internuclear distance).

Fas-L on the cytotoxic T cell binds to its receptor, the Fas protein on the tumor cells, an apoptotic signaling pathway in the tumor cells becomes activated, which also leads to tumor cell death.
