Dimer - an overview ScienceDirect Topics
WebDimer definition, a molecule composed of two identical, simpler molecules. See more. A dimer (di-, "two" + -mer, "parts") is an oligomer consisting of two monomers joined by bonds that can be either strong or weak, covalent or intermolecular. Dimers also have significant implications in polymer chemistry; inorganic chemistry, and biochemistry. The term homodimer is used when the two … See more Anhydrous carboxylic acids form dimers by hydrogen bonding of the acidic hydrogen and the carbonyl oxygen. For example, acetic acid forms a dimer in the gas phase, where the monomer units are held together by See more In the context of polymers, "dimer" also refers to the degree of polymerization 2, regardless of the stoichiometry or condensation reactions. One case where … See more Pyrimidine dimers Pyrimidine dimers (also known as thymine dimers) are formed by a photochemical reaction from pyrimidine DNA bases when exposed to … See more Molecular dimers are often formed by the reaction of two identical compounds e.g.: 2A → A−A. In this example, monomer "A" is said to dimerize to give the dimer "A−A". An example is a See more Group 13 dimers Boranes Diborane (B2H6) is a classic example of an inorganic dimer.
