conjugation

conjugation

[kon-juh-gey-shuhn]
conjugation: see inflection.
conjugation, in genetics: see recombination.

Interaction of adjacent bonds in a chemical compound having alternating single and double covalent bonds. The conjugated bonds show modified characteristics because of increased electron delocalization and sharing. Conjugation occurs, for example, within a molecule containing a chain of carbon atoms linked by alternating single and double bonds. Such a conjugated system often gives rise to substances with intense colours—e.g., the biological pigments called carotenes. Another example is the carboxyl group (see carboxylic acid; functional group), in which the double bond of the carbonyl group (singlehorzbondCdoublehorzbondO) is adjacent to the single bond attaching the hydroxyl group (singlehorzbondOH) to the carbon atom.
