Chapter 5: Biological Molecules

  • Page ID
  • In biological systems, the ligands in metal coordination complexes include small molecules like drugs, lipids, and amino acids. In addition, larger biomolecules like DNA, RNA, peptides/proteins, and carbohydrates also serve as ligands. These larger biomolecules are often polydentate chelators and they have structural constraints that influence the coordination geometry or number of ligands that bind to metals. In this chapter, we will start with the very basics of biomolecule structure.
