Three different small organic ligands can each bind to a protein but only one ligand can bind to the protein at a time. The KD for ligand 1 binding to the protein is 100 nM The KD for ligand 2 binding to the protein is 72 nM The KD for ligand 3 binding to the protein is 9 nM Which of the three ligands binds tightest to the protein?

Explanation:

The binding affinity in ligand binding is measured using the equilibrium dissociation constant (KD).

The larger the dissociation constant value, the more weakly the target molecule and ligand are attracted to and bind to one another.

This, in this case study, the ligand that binds tightest to the protein is ligand 3 with a binding affinity of 9nM followed by Ligand 2 and then 1.

i would say the prokaryotic cells the prokaryotic cells are less complex, are usually found only in unicellular organisms and have more limited capabilities than eukaryotic cells.

all matter is made up of atoms

in any element all atoms are the same

elements in a compound are always in a constant ratio: apex
