Relationships between hydrogen bonds and halogen bonds in biological systems
1Department of Biochemistry and Molecular Biology, Colorado State University, Fort Collins, Colorado 80523-1870, USA.
Summary
Halogen bonding (XB) is crucial in biology, influencing drug design and biomolecular engineering. Understanding its interplay with hydrogen bonds (HB) is key to controlling molecular interactions and functions.
Area of Science:
- Biochemistry
- Medicinal Chemistry
- Structural Biology
Background:
- Halogen bonding (XB) is increasingly recognized for its significant role in biological molecule recognition and assembly.
- The ubiquitous hydrogen bond (HB) is a well-established interaction in biological systems.
Purpose of the Study:
- To explore the complex relationships between halogen bonding (XB) and hydrogen bonding (HB) in biological systems.
- To assess the potential of XBs to replace, compete with, or act independently of HBs.
Main Methods:
- Literature review focusing on the comparative roles of XB and HB in biological contexts.
- Analysis of existing data and theoretical considerations regarding the interplay of these non-covalent interactions.
Main Results:
- XB interactions offer unique properties that can complement or substitute for HBs in specific biological scenarios.
- The relationship between XB and HB is complex, involving competition, synergy, and independent action depending on the molecular context.
Conclusions:
- A comprehensive understanding of the XB-HB relationship is essential for advancing rational drug design and biomolecular engineering.
- Harnessing the distinct characteristics of XBs can lead to improved control over inhibitor affinity, target recognition, and biomolecular structure/function.

00:26Hydrogen Bonds
Hydrogen BondsHydrogen bonds are weak attractions between atoms that have formed other chemical bonds. One of these atoms is electronegative, like oxygen, and has a partial negative charge. The other is a hydrogen atom that has bonded with another electronegative atom and has a partial positive charge.Hydrogen Bonds Control the World!Because hydrogen has very weak electronegativity when it binds with a strongly electronegative atom, such as oxygen or nitrogen, electrons in the bond are...

Overview of Valence Bond Theory
02:42Valence Bond Theory
Coordination compounds and complexes exhibit different colors, geometries, and magnetic behavior, depending on the metal atom/ion and ligands from which they are composed. In an attempt to explain the bonding and structure of coordination complexes, Linus Pauling proposed the valence bond theory, or VBT, using the concepts of hybridization and the overlapping of the atomic orbitals. According to VBT, the central metal atom or ion (Lewis acid) hybridizes to provide empty orbitals of suitable...
02:45Alkyl Halides
Structural Properties
Alkyl halides are halogen-substituted alkanes wherein one or more hydrogen atoms of an alkane is replaced by a halogen atom such as fluorine, chlorine, bromine, or iodine. The carbon atom in an alkyl halide is bonded to the halogen atom, which is sp3-hybridized and exhibits a tetrahedral shape.
Unlike alkyl halides, compounds in which a halogen atom is bonded to an sp2 -hybridized carbon atom of a carbon-carbon double bond (C=C) are called vinyl halides. Whereas aryl...

02:41Formation of Halohydrin from Alkenes
An alkene, such as propene, reacts with bromine in the presence of water to yield a halohydrin. Halohydrins contain a halogen and a hydroxyl group attached to adjacent carbons. When the halogen is bromine, it is called a bromohydrin, while a chlorohydrin has chlorine as the halogen.
01:04Hydrogen Bonds
A hydrogen bond is formed when a weakly positive hydrogen atom already bonded to one electronegative atom (for example, the oxygen in the water molecule) is attracted to another electronegative atom from another polar molecule, such as water (H2O), hydrogen fluoride (HF), or ammonia (NH3). The huge electronegativity difference between the H atom (2.1) and the atom to which it is bonded (4.0 for an F atom, 3.5 for an O atom, or 3.0 for an N atom), combined with the very small size of an H atom...
