A weak bond between a hydrogen atom attached to one oxygen or nitrogen atom and another oxygen or nitrogen atom. Important in water, proteins, and chromosomes hydrogen bonding.
Weak chemical bond involving the sharing of an electron with a hydrogen atom that increases the overall stability of a molecule; important in the specificity of base pairing in nucleic acids (DNA, RNA) and in the determination of protein shape.
A weak electrostatic bond formed by linking a hydrogen atom between two electronegative atoms (e.g. nitrogen or oxygen). The large number of hydrogen bonds in proteins and nucleic acids are responsible for maintaining the stable molecular structure of these compounds.
The weak attraction of a covalently bonded hydrogen to nearby oxygen or nitrogen atoms in the same or a different molecule. Hydrogen bonds give water its cohesiveness and its surface tension. These bonds also help maintain the three-dimensional shape of proteins and nucleic acids; such shape is essential to their functioning.
A weak, physical, cross-link side bond that is easily broken by water or heat.
