# dimerizationZoomA-Z

## Subject - Organic Chemistry

In chemistry, dimerization is the combination of two identical molecules to form a single new molecule known as a . Examples are the Aldol reaction of acetaldehyde ($H3C-CHO$) yielding an aldol ($H3C-CHOH-CH2-CHO$) and the formation of alkenes from carbenes.

Of importance in biology is the dimerization of neighboring thymine residues of DNA caused by UV light. This reaction forms thymine dimers that interfere with base pairing during DNA replication

## Subject - Biochemistry

In biochemistry and molecular biology, the term dimer is used to describe the aggregation of individual components of a protein that is built up from several subunits. The aggregation of two identical subunits is called homodimerization. Heterodimerization on the other hand involves the aggregation of two different subunits.
