Study Notes
Bioinorganic Metals
- Bioinorganic chemistry applies coordination chemistry principles to understand biological pathways and interactions between metal ions and ligands with biological functions.
- The human body requires many metals for its functions.
- Alkali metal ions (e.g., sodium, potassium) regulate osmotic control and nerve actions.
- Alkali earth metal (e.g., magnesium) is found in metalloenzymes and aids muscle movement
- Calcium is essential for bone and teeth structure.
- First-row transition metals are found in trace amounts but are important for homeostasis.
- The abundance of essential metals varies between organisms, with iron and zinc being the most prevalent in humans.
Biological Molecules as Ligands
- Biological systems contain abundant amino acids and proteins as ligands.
- There are 21 known amino acids.
- The α-carbon's carboxylic acid and amine groups do not form coordination bonds to a metal, but the various side chain functionalities can provide coordination sites to different metals.
- Side chains containing N, O, or S atoms (with lone pairs of electrons) act as excellent ligands for first-row transition metals.
- Histidine, with an imidazole group in its side chain, has two potential coordination sites for a transition metal.
- Both nitrogen atoms (δ and ε) in Histidine can coordinate to a metal as monodentate donors, favoring Fe, Cu, and Zn complex formation.
Prosthetic Groups
- Prosthetic groups are non-amino acid complexes essential for protein activity.
- Examples include the porphyrin group (Haem moiety) found in Haemoglobin and the corrin macrocyclic ligand found in Cobalamin.
- Porphyrin acts as a tetra-dentate ligand through its four nitrogen atoms in a 16-membered atom ring.
- Corrin, with a slightly smaller ring size (15-membered atom ring), also acts as a tetra-dentate ligand through its four nitrogen atoms.
- Metalloproteins contain metal ions within the prosthetic group, with common ones includes Fe (Haemoglobin) and Co (Cobalamin).
Metals in the Human Body
- The elements used by biology are categorized based on their prevalence: green for widespread use, blue for trace/suspected use, and orange for very rare use.
- Metals used in the human body include:
- Vanadium (V): found in nitrogenases.
- Chromium (Cr): involved in glucose metabolism.
- Manganese (Mn): found in phosphatases and participates in redox activity in plants.
- Iron (Fe): crucial for hemoglobin/myoglobin, iron storage proteins (ferritin, transferrin), and transport processes.
- Cobalt (Co): a component of Vitamin B12.
- Nickel (Ni): found in ureases.
- Copper (Cu): participates in electron transfer systems and transport proteins
- Zinc (Zn): found in enzymes like alcohol dehydrogenase and carbonic anhydrase.
