... earth would not exist without the many bonds observed throughout Biochemistry. There is two types of force the intramolecular force which exist between the atoms in a molecule such as Covalent, Ionic and Metallic bonding, the second force being intermolecular force that exist between neighboring molecules such a Hydrogen bonding, dispersion forces and dipole-dipole bonds. Hydrogen bonding being a weak chemical ... bond is one of the most important bonds present in essential biological molecule. Nearly all molecules have London dispersion ... a specific active site where complementary sub...

... instead of a CH2-OH. The pectin chain is held together by a bond between carbon 1 of one galacturonic acid and carbon 4 of the next one and so on. Pectinase splits the bonds between these galacturonic acids to shorten the pectin chain from large fragments in to many more small fragments. The actual catalytic mechanism introduces water so pectinase is known as a hydrolytic ... the folded structure forms the catalytic or active site. However this folded structure will generally be held together by non-covalent interactions unlike the covalent bonds that hold the amino acid links together....

... electron. This causes an immense permanent dipole that will attract molecules with a similar dipole. Although H-bonding is still only approximately one tenth of the strength of a covalent bond, it is the strongest of these forces by far. Water stands out even from the H-bonding compounds ( H2O, HF, NH3 ) because of its structure ... needle, more dense than water, can be made to float on its surface because of this strong surface tension. It also accounts for its viscosity, as the bonds are stronger, the molecules are harder to move and separate, and this makes the liquid "harder to pour...
